Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473892, here are decompositions:

5 + 31473887 = 31473892
29 + 31473863 = 31473892
53 + 31473839 = 31473892
83 + 31473809 = 31473892
113 + 31473779 = 31473892
293 + 31473599 = 31473892
311 + 31473581 = 31473892
479 + 31473413 = 31473892

Showing the first eight; more decompositions exist.
