Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545328, here are decompositions:
- 5 + 31545323 = 31545328
- 11 + 31545317 = 31545328
- 29 + 31545299 = 31545328
- 41 + 31545287 = 31545328
- 107 + 31545221 = 31545328
- 137 + 31545191 = 31545328
- 359 + 31544969 = 31545328
- 449 + 31544879 = 31545328
Showing the first eight; more decompositions exist.
