Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122412, here are decompositions:
- 11 + 122401 = 122412
- 13 + 122399 = 122412
- 19 + 122393 = 122412
- 23 + 122389 = 122412
- 89 + 122323 = 122412
- 113 + 122299 = 122412
- 139 + 122273 = 122412
- 149 + 122263 = 122412
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 122,412 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 122412 first appears in π at position 191,119 of the decimal expansion (the 191,119ordinal-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.
