Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42564, here are decompositions:
- 7 + 42557 = 42564
- 31 + 42533 = 42564
- 73 + 42491 = 42564
- 97 + 42467 = 42564
- 101 + 42463 = 42564
- 103 + 42461 = 42564
- 107 + 42457 = 42564
- 113 + 42451 = 42564
Showing the first eight; more decompositions exist.

The digit sequence 42564 first appears in π at position 207,300 of the decimal expansion (the 207,300ordinal-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.
