Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177818, here are decompositions:
- 7 + 177811 = 177818
- 31 + 177787 = 177818
- 79 + 177739 = 177818
- 127 + 177691 = 177818
- 139 + 177679 = 177818
- 229 + 177589 = 177818
- 307 + 177511 = 177818
- 331 + 177487 = 177818
Showing the first eight; more decompositions exist.
