Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31350, here are decompositions:
- 13 + 31337 = 31350
- 17 + 31333 = 31350
- 23 + 31327 = 31350
- 29 + 31321 = 31350
- 31 + 31319 = 31350
- 43 + 31307 = 31350
- 73 + 31277 = 31350
- 79 + 31271 = 31350
Showing the first eight; more decompositions exist.
