Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473762, here are decompositions:

29 + 31473733 = 31473762
59 + 31473703 = 31473762
163 + 31473599 = 31473762
179 + 31473583 = 31473762
181 + 31473581 = 31473762
233 + 31473529 = 31473762
239 + 31473523 = 31473762
283 + 31473479 = 31473762

Showing the first eight; more decompositions exist.
