Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472126, here are decompositions:
- 3 + 31472123 = 31472126
- 19 + 31472107 = 31472126
- 73 + 31472053 = 31472126
- 97 + 31472029 = 31472126
- 193 + 31471933 = 31472126
- 277 + 31471849 = 31472126
- 463 + 31471663 = 31472126
- 487 + 31471639 = 31472126
Showing the first eight; more decompositions exist.
