Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56642, here are decompositions:
- 13 + 56629 = 56642
- 31 + 56611 = 56642
- 43 + 56599 = 56642
- 73 + 56569 = 56642
- 109 + 56533 = 56642
- 139 + 56503 = 56642
- 163 + 56479 = 56642
- 199 + 56443 = 56642
Showing the first eight; more decompositions exist.
