Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56490, here are decompositions:
- 11 + 56479 = 56490
- 13 + 56477 = 56490
- 17 + 56473 = 56490
- 23 + 56467 = 56490
- 37 + 56453 = 56490
- 47 + 56443 = 56490
- 53 + 56437 = 56490
- 59 + 56431 = 56490
Showing the first eight; more decompositions exist.
