Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545148, here are decompositions:
- 29 + 31545119 = 31545148
- 179 + 31544969 = 31545148
- 269 + 31544879 = 31545148
- 389 + 31544759 = 31545148
- 431 + 31544717 = 31545148
- 491 + 31544657 = 31545148
- 587 + 31544561 = 31545148
- 617 + 31544531 = 31545148
Showing the first eight; more decompositions exist.
