Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535448, here are decompositions:
- 19 + 31535429 = 31535448
- 29 + 31535419 = 31535448
- 31 + 31535417 = 31535448
- 37 + 31535411 = 31535448
- 67 + 31535381 = 31535448
- 71 + 31535377 = 31535448
- 107 + 31535341 = 31535448
- 127 + 31535321 = 31535448
Showing the first eight; more decompositions exist.
