Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61646, here are decompositions:
- 3 + 61643 = 61646
- 19 + 61627 = 61646
- 37 + 61609 = 61646
- 43 + 61603 = 61646
- 103 + 61543 = 61646
- 127 + 61519 = 61646
- 139 + 61507 = 61646
- 163 + 61483 = 61646
Showing the first eight; more decompositions exist.

The digit sequence 61646 first appears in π at position 360,114 of the decimal expansion (the 360,114ordinal-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.
