Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31306, here are decompositions:
- 29 + 31277 = 31306
- 47 + 31259 = 31306
- 53 + 31253 = 31306
- 59 + 31247 = 31306
- 83 + 31223 = 31306
- 113 + 31193 = 31306
- 167 + 31139 = 31306
- 227 + 31079 = 31306
Showing the first eight; more decompositions exist.
