Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559922, here are decompositions:
- 11 + 31559911 = 31559922
- 61 + 31559861 = 31559922
- 71 + 31559851 = 31559922
- 73 + 31559849 = 31559922
- 89 + 31559833 = 31559922
- 101 + 31559821 = 31559922
- 109 + 31559813 = 31559922
- 113 + 31559809 = 31559922
Showing the first eight; more decompositions exist.
