Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450136, here are decompositions:

19 + 31450117 = 31450136
37 + 31450099 = 31450136
43 + 31450093 = 31450136
79 + 31450057 = 31450136
103 + 31450033 = 31450136
199 + 31449937 = 31450136
283 + 31449853 = 31450136
313 + 31449823 = 31450136

Showing the first eight; more decompositions exist.
