Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540484, here are decompositions:
- 13 + 31540471 = 31540484
- 43 + 31540441 = 31540484
- 67 + 31540417 = 31540484
- 223 + 31540261 = 31540484
- 271 + 31540213 = 31540484
- 277 + 31540207 = 31540484
- 337 + 31540147 = 31540484
- 421 + 31540063 = 31540484
Showing the first eight; more decompositions exist.
