Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31394, here are decompositions:
- 3 + 31391 = 31394
- 7 + 31387 = 31394
- 37 + 31357 = 31394
- 61 + 31333 = 31394
- 67 + 31327 = 31394
- 73 + 31321 = 31394
- 127 + 31267 = 31394
- 157 + 31237 = 31394
Showing the first eight; more decompositions exist.
