Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31010, here are decompositions:
- 61 + 30949 = 31010
- 73 + 30937 = 31010
- 79 + 30931 = 31010
- 139 + 30871 = 31010
- 151 + 30859 = 31010
- 157 + 30853 = 31010
- 181 + 30829 = 31010
- 193 + 30817 = 31010
Showing the first eight; more decompositions exist.
