Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31070, here are decompositions:
- 7 + 31063 = 31070
- 19 + 31051 = 31070
- 31 + 31039 = 31070
- 37 + 31033 = 31070
- 139 + 30931 = 31070
- 199 + 30871 = 31070
- 211 + 30859 = 31070
- 229 + 30841 = 31070
Showing the first eight; more decompositions exist.
