Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544458, here are decompositions:
- 41 + 31544417 = 31544458
- 251 + 31544207 = 31544458
- 269 + 31544189 = 31544458
- 359 + 31544099 = 31544458
- 401 + 31544057 = 31544458
- 419 + 31544039 = 31544458
- 461 + 31543997 = 31544458
- 467 + 31543991 = 31544458
Showing the first eight; more decompositions exist.
