Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19536, here are decompositions:
- 5 + 19531 = 19536
- 29 + 19507 = 19536
- 47 + 19489 = 19536
- 53 + 19483 = 19536
- 59 + 19477 = 19536
- 67 + 19469 = 19536
- 73 + 19463 = 19536
- 79 + 19457 = 19536
Showing the first eight; more decompositions exist.

The digit sequence 19536 first appears in π at position 130,922 of the decimal expansion (the 130,922ordinal-suffix:nd 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.
