Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572124, here are decompositions:
- 17 + 572107 = 572124
- 31 + 572093 = 572124
- 37 + 572087 = 572124
- 61 + 572063 = 572124
- 71 + 572053 = 572124
- 73 + 572051 = 572124
- 83 + 572041 = 572124
- 97 + 572027 = 572124
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 572,124 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 572124 first appears in π at position 251,785 of the decimal expansion (the 251,785ordinal-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.
