Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582980, here are decompositions:
- 19 + 31582961 = 31582980
- 29 + 31582951 = 31582980
- 31 + 31582949 = 31582980
- 43 + 31582937 = 31582980
- 67 + 31582913 = 31582980
- 73 + 31582907 = 31582980
- 83 + 31582897 = 31582980
- 89 + 31582891 = 31582980
Showing the first eight; more decompositions exist.
