Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122624, here are decompositions:
- 13 + 122611 = 122624
- 67 + 122557 = 122624
- 97 + 122527 = 122624
- 127 + 122497 = 122624
- 181 + 122443 = 122624
- 223 + 122401 = 122624
- 277 + 122347 = 122624
- 373 + 122251 = 122624
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 122,624 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 122624 first appears in π at position 59,831 of the decimal expansion (the 59,831ordinal-suffix:st 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.
