Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479454, here are decompositions:

257 + 31479197 = 31479454
353 + 31479101 = 31479454
521 + 31478933 = 31479454
647 + 31478807 = 31479454
887 + 31478567 = 31479454
971 + 31478483 = 31479454
983 + 31478471 = 31479454
1061 + 31478393 = 31479454

Showing the first eight; more decompositions exist.
