Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477456, here are decompositions:
- 29 + 31477427 = 31477456
- 107 + 31477349 = 31477456
- 167 + 31477289 = 31477456
- 293 + 31477163 = 31477456
- 389 + 31477067 = 31477456
- 509 + 31476947 = 31477456
- 863 + 31476593 = 31477456
- 947 + 31476509 = 31477456
Showing the first eight; more decompositions exist.
