Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122436, here are decompositions:
- 37 + 122399 = 122436
- 43 + 122393 = 122436
- 47 + 122389 = 122436
- 73 + 122363 = 122436
- 89 + 122347 = 122436
- 109 + 122327 = 122436
- 113 + 122323 = 122436
- 137 + 122299 = 122436
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 122,436 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 122436 first appears in π at position 75,497 of the decimal expansion (the 75,497ordinal-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.
