Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545348, here are decompositions:
- 5 + 31545343 = 31545348
- 17 + 31545331 = 31545348
- 19 + 31545329 = 31545348
- 31 + 31545317 = 31545348
- 61 + 31545287 = 31545348
- 127 + 31545221 = 31545348
- 137 + 31545211 = 31545348
- 157 + 31545191 = 31545348
Showing the first eight; more decompositions exist.
