Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450094, here are decompositions:

37 + 31450057 = 31450094
61 + 31450033 = 31450094
73 + 31450021 = 31450094
103 + 31449991 = 31450094
127 + 31449967 = 31450094
157 + 31449937 = 31450094
163 + 31449931 = 31450094
223 + 31449871 = 31450094

Showing the first eight; more decompositions exist.
