Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480182, here are decompositions:

53 + 31480129 = 31480182
79 + 31480103 = 31480182
103 + 31480079 = 31480182
163 + 31480019 = 31480182
233 + 31479949 = 31480182
353 + 31479829 = 31480182
379 + 31479803 = 31480182
389 + 31479793 = 31480182

Showing the first eight; more decompositions exist.
