Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163178, here are decompositions:
- 7 + 163171 = 163178
- 31 + 163147 = 163178
- 61 + 163117 = 163178
- 151 + 163027 = 163178
- 157 + 163021 = 163178
- 181 + 162997 = 163178
- 241 + 162937 = 163178
- 271 + 162907 = 163178
Showing the first eight; more decompositions exist.
