Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471068, here are decompositions:
- 17 + 31471051 = 31471068
- 37 + 31471031 = 31471068
- 61 + 31471007 = 31471068
- 67 + 31471001 = 31471068
- 71 + 31470997 = 31471068
- 127 + 31470941 = 31471068
- 151 + 31470917 = 31471068
- 157 + 31470911 = 31471068
Showing the first eight; more decompositions exist.
