Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31182, here are decompositions:
- 5 + 31177 = 31182
- 23 + 31159 = 31182
- 29 + 31153 = 31182
- 31 + 31151 = 31182
- 43 + 31139 = 31182
- 59 + 31123 = 31182
- 61 + 31121 = 31182
- 101 + 31081 = 31182
Showing the first eight; more decompositions exist.
