Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112420, here are decompositions:
- 17 + 112403 = 112420
- 23 + 112397 = 112420
- 59 + 112361 = 112420
- 71 + 112349 = 112420
- 83 + 112337 = 112420
- 89 + 112331 = 112420
- 131 + 112289 = 112420
- 167 + 112253 = 112420
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 112,420 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 112420 first appears in π at position 935,276 of the decimal expansion (the 935,276ordinal-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.
