Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450082, here are decompositions:

61 + 31450021 = 31450082
151 + 31449931 = 31450082
211 + 31449871 = 31450082
229 + 31449853 = 31450082
331 + 31449751 = 31450082
409 + 31449673 = 31450082
463 + 31449619 = 31450082
619 + 31449463 = 31450082

Showing the first eight; more decompositions exist.
