Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473412, here are decompositions:

53 + 31473359 = 31473412
149 + 31473263 = 31473412
239 + 31473173 = 31473412
251 + 31473161 = 31473412
449 + 31472963 = 31473412
521 + 31472891 = 31473412
563 + 31472849 = 31473412
599 + 31472813 = 31473412

Showing the first eight; more decompositions exist.
