Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564864, here are decompositions:
- 37 + 564827 = 564864
- 67 + 564797 = 564864
- 71 + 564793 = 564864
- 103 + 564761 = 564864
- 151 + 564713 = 564864
- 163 + 564701 = 564864
- 193 + 564671 = 564864
- 197 + 564667 = 564864
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 564,864 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 564864 first appears in π at position 326,967 of the decimal expansion (the 326,967ordinal-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.
