Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124564, here are decompositions:
- 3 + 124561 = 124564
- 23 + 124541 = 124564
- 71 + 124493 = 124564
- 131 + 124433 = 124564
- 137 + 124427 = 124564
- 197 + 124367 = 124564
- 227 + 124337 = 124564
- 263 + 124301 = 124564
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 124,564 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 124564 first appears in π at position 840,270 of the decimal expansion (the 840,270ordinal-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.
