Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452514, here are decompositions:

17 + 31452497 = 31452514
53 + 31452461 = 31452514
113 + 31452401 = 31452514
173 + 31452341 = 31452514
281 + 31452233 = 31452514
311 + 31452203 = 31452514
383 + 31452131 = 31452514
521 + 31451993 = 31452514

Showing the first eight; more decompositions exist.
