Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451034, here are decompositions:

5 + 31451029 = 31451034
37 + 31450997 = 31451034
67 + 31450967 = 31451034
73 + 31450961 = 31451034
137 + 31450897 = 31451034
191 + 31450843 = 31451034
193 + 31450841 = 31451034
211 + 31450823 = 31451034

Showing the first eight; more decompositions exist.
