Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123284, here are decompositions:
- 67 + 123217 = 123284
- 157 + 123127 = 123284
- 163 + 123121 = 123284
- 193 + 123091 = 123284
- 277 + 123007 = 123284
- 283 + 123001 = 123284
- 313 + 122971 = 123284
- 331 + 122953 = 123284
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 123,284 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 123284 first appears in π at position 692,077 of the decimal expansion (the 692,077ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
