Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472892, here are decompositions:
- 5 + 31472887 = 31472892
- 13 + 31472879 = 31472892
- 41 + 31472851 = 31472892
- 43 + 31472849 = 31472892
- 53 + 31472839 = 31472892
- 79 + 31472813 = 31472892
- 193 + 31472699 = 31472892
- 223 + 31472669 = 31472892
Showing the first eight; more decompositions exist.
