Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31088, here are decompositions:
- 7 + 31081 = 31088
- 19 + 31069 = 31088
- 37 + 31051 = 31088
- 139 + 30949 = 31088
- 151 + 30937 = 31088
- 157 + 30931 = 31088
- 229 + 30859 = 31088
- 271 + 30817 = 31088
Showing the first eight; more decompositions exist.
