Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19768, here are decompositions:
- 5 + 19763 = 19768
- 17 + 19751 = 19768
- 29 + 19739 = 19768
- 41 + 19727 = 19768
- 59 + 19709 = 19768
- 71 + 19697 = 19768
- 107 + 19661 = 19768
- 191 + 19577 = 19768
Showing the first eight; more decompositions exist.

The digit sequence 19768 first appears in π at position 211,807 of the decimal expansion (the 211,807ordinal-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.
