Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451094, here are decompositions:

47 + 31451047 = 31451094
61 + 31451033 = 31451094
97 + 31450997 = 31451094
127 + 31450967 = 31451094
197 + 31450897 = 31451094
251 + 31450843 = 31451094
271 + 31450823 = 31451094
293 + 31450801 = 31451094

Showing the first eight; more decompositions exist.
