Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530448, here are decompositions:
- 11 + 31530437 = 31530448
- 29 + 31530419 = 31530448
- 71 + 31530377 = 31530448
- 101 + 31530347 = 31530448
- 107 + 31530341 = 31530448
- 137 + 31530311 = 31530448
- 179 + 31530269 = 31530448
- 251 + 31530197 = 31530448
Showing the first eight; more decompositions exist.
