Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1768, here are decompositions:
- 47 + 1721 = 1768
- 59 + 1709 = 1768
- 71 + 1697 = 1768
- 101 + 1667 = 1768
- 131 + 1637 = 1768
- 149 + 1619 = 1768
- 167 + 1601 = 1768
- 197 + 1571 = 1768
Showing the first eight; more decompositions exist.

The digit sequence 1768 first appears in π at position 16,009 of the decimal expansion (the 16,009ordinal-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.
