Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473660, here are decompositions:

61 + 31473599 = 31473660
67 + 31473593 = 31473660
79 + 31473581 = 31473660
131 + 31473529 = 31473660
137 + 31473523 = 31473660
173 + 31473487 = 31473660
181 + 31473479 = 31473660
223 + 31473437 = 31473660

Showing the first eight; more decompositions exist.
