Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471906, here are decompositions:
- 5 + 31471901 = 31471906
- 23 + 31471883 = 31471906
- 83 + 31471823 = 31471906
- 107 + 31471799 = 31471906
- 239 + 31471667 = 31471906
- 269 + 31471637 = 31471906
- 383 + 31471523 = 31471906
- 449 + 31471457 = 31471906
Showing the first eight; more decompositions exist.
