Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451054, here are decompositions:

7 + 31451047 = 31451054
157 + 31450897 = 31451054
163 + 31450891 = 31451054
211 + 31450843 = 31451054
331 + 31450723 = 31451054
433 + 31450621 = 31451054
571 + 31450483 = 31451054
631 + 31450423 = 31451054

Showing the first eight; more decompositions exist.
