Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473566, here are decompositions:

37 + 31473529 = 31473566
43 + 31473523 = 31473566
79 + 31473487 = 31473566
109 + 31473457 = 31473566
283 + 31473283 = 31473566
349 + 31473217 = 31473566
379 + 31473187 = 31473566
457 + 31473109 = 31473566

Showing the first eight; more decompositions exist.
