Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451048, here are decompositions:

19 + 31451029 = 31451048
151 + 31450897 = 31451048
157 + 31450891 = 31451048
619 + 31450429 = 31451048
661 + 31450387 = 31451048
757 + 31450291 = 31451048
829 + 31450219 = 31451048
907 + 31450141 = 31451048

Showing the first eight; more decompositions exist.
