Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31166, here are decompositions:
- 7 + 31159 = 31166
- 13 + 31153 = 31166
- 19 + 31147 = 31166
- 43 + 31123 = 31166
- 97 + 31069 = 31166
- 103 + 31063 = 31166
- 127 + 31039 = 31166
- 229 + 30937 = 31166
Showing the first eight; more decompositions exist.
