Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594078, here are decompositions:
- 17 + 31594061 = 31594078
- 29 + 31594049 = 31594078
- 239 + 31593839 = 31594078
- 281 + 31593797 = 31594078
- 311 + 31593767 = 31594078
- 359 + 31593719 = 31594078
- 389 + 31593689 = 31594078
- 431 + 31593647 = 31594078
Showing the first eight; more decompositions exist.
