Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465182, here are decompositions:

5 + 31465177 = 31465182
29 + 31465153 = 31465182
53 + 31465129 = 31465182
59 + 31465123 = 31465182
71 + 31465111 = 31465182
83 + 31465099 = 31465182
113 + 31465069 = 31465182
149 + 31465033 = 31465182

Showing the first eight; more decompositions exist.
