Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55818, here are decompositions:
- 5 + 55813 = 55818
- 11 + 55807 = 55818
- 19 + 55799 = 55818
- 31 + 55787 = 55818
- 97 + 55721 = 55818
- 101 + 55717 = 55818
- 107 + 55711 = 55818
- 127 + 55691 = 55818
Showing the first eight; more decompositions exist.
