Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541448, here are decompositions:
- 11 + 31541437 = 31541448
- 19 + 31541429 = 31541448
- 31 + 31541417 = 31541448
- 47 + 31541401 = 31541448
- 89 + 31541359 = 31541448
- 101 + 31541347 = 31541448
- 151 + 31541297 = 31541448
- 167 + 31541281 = 31541448
Showing the first eight; more decompositions exist.
