Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540434, here are decompositions:
- 17 + 31540417 = 31540434
- 71 + 31540363 = 31540434
- 137 + 31540297 = 31540434
- 173 + 31540261 = 31540434
- 193 + 31540241 = 31540434
- 223 + 31540211 = 31540434
- 227 + 31540207 = 31540434
- 271 + 31540163 = 31540434
Showing the first eight; more decompositions exist.
