Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123628, here are decompositions:
- 47 + 123581 = 123628
- 101 + 123527 = 123628
- 137 + 123491 = 123628
- 149 + 123479 = 123628
- 179 + 123449 = 123628
- 227 + 123401 = 123628
- 251 + 123377 = 123628
- 317 + 123311 = 123628
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 123,628 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 123628 first appears in π at position 479,890 of the decimal expansion (the 479,890ordinal-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.
