Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56540, here are decompositions:
- 7 + 56533 = 56540
- 13 + 56527 = 56540
- 31 + 56509 = 56540
- 37 + 56503 = 56540
- 61 + 56479 = 56540
- 67 + 56473 = 56540
- 73 + 56467 = 56540
- 97 + 56443 = 56540
Showing the first eight; more decompositions exist.
