Goldbach decomposition

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.
