Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122620, here are decompositions:
- 11 + 122609 = 122620
- 23 + 122597 = 122620
- 41 + 122579 = 122620
- 59 + 122561 = 122620
- 131 + 122489 = 122620
- 149 + 122471 = 122620
- 167 + 122453 = 122620
- 227 + 122393 = 122620
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 122,620 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 122620 first appears in π at position 943,684 of the decimal expansion (the 943,684ordinal-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.
