Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473766, here are decompositions:

59 + 31473707 = 31473766
167 + 31473599 = 31473766
173 + 31473593 = 31473766
353 + 31473413 = 31473766
503 + 31473263 = 31473766
557 + 31473209 = 31473766
563 + 31473203 = 31473766
593 + 31473173 = 31473766

Showing the first eight; more decompositions exist.
