Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473850, here are decompositions:

3 + 31473847 = 31473850
11 + 31473839 = 31473850
41 + 31473809 = 31473850
71 + 31473779 = 31473850
251 + 31473599 = 31473850
257 + 31473593 = 31473850
269 + 31473581 = 31473850
491 + 31473359 = 31473850

Showing the first eight; more decompositions exist.
