Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473964, here are decompositions:

47 + 31473917 = 31473964
101 + 31473863 = 31473964
257 + 31473707 = 31473964
383 + 31473581 = 31473964
701 + 31473263 = 31473964
761 + 31473203 = 31473964
773 + 31473191 = 31473964
857 + 31473107 = 31473964

Showing the first eight; more decompositions exist.
