Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31214, here are decompositions:
- 31 + 31183 = 31214
- 37 + 31177 = 31214
- 61 + 31153 = 31214
- 67 + 31147 = 31214
- 151 + 31063 = 31214
- 163 + 31051 = 31214
- 181 + 31033 = 31214
- 277 + 30937 = 31214
Showing the first eight; more decompositions exist.
