Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541400, here are decompositions:
- 41 + 31541359 = 31541400
- 53 + 31541347 = 31541400
- 103 + 31541297 = 31541400
- 131 + 31541269 = 31541400
- 157 + 31541243 = 31541400
- 167 + 31541233 = 31541400
- 227 + 31541173 = 31541400
- 239 + 31541161 = 31541400
Showing the first eight; more decompositions exist.
