Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457326, here are decompositions:
- 23 + 31457303 = 31457326
- 29 + 31457297 = 31457326
- 59 + 31457267 = 31457326
- 167 + 31457159 = 31457326
- 227 + 31457099 = 31457326
- 233 + 31457093 = 31457326
- 317 + 31457009 = 31457326
- 389 + 31456937 = 31457326
Showing the first eight; more decompositions exist.
