Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450034, here are decompositions:

3 + 31450031 = 31450034
13 + 31450021 = 31450034
43 + 31449991 = 31450034
67 + 31449967 = 31450034
97 + 31449937 = 31450034
103 + 31449931 = 31450034
163 + 31449871 = 31450034
181 + 31449853 = 31450034

Showing the first eight; more decompositions exist.
