Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56820, here are decompositions:
- 7 + 56813 = 56820
- 11 + 56809 = 56820
- 13 + 56807 = 56820
- 37 + 56783 = 56820
- 41 + 56779 = 56820
- 47 + 56773 = 56820
- 53 + 56767 = 56820
- 73 + 56747 = 56820
Showing the first eight; more decompositions exist.
