Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558032, here are decompositions:
- 13 + 31558019 = 31558032
- 19 + 31558013 = 31558032
- 61 + 31557971 = 31558032
- 71 + 31557961 = 31558032
- 73 + 31557959 = 31558032
- 101 + 31557931 = 31558032
- 113 + 31557919 = 31558032
- 151 + 31557881 = 31558032
Showing the first eight; more decompositions exist.
