Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545346, here are decompositions:
- 3 + 31545343 = 31545346
- 17 + 31545329 = 31545346
- 23 + 31545323 = 31545346
- 29 + 31545317 = 31545346
- 47 + 31545299 = 31545346
- 59 + 31545287 = 31545346
- 113 + 31545233 = 31545346
- 227 + 31545119 = 31545346
Showing the first eight; more decompositions exist.
