Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473610, here are decompositions:

11 + 31473599 = 31473610
17 + 31473593 = 31473610
29 + 31473581 = 31473610
131 + 31473479 = 31473610
173 + 31473437 = 31473610
197 + 31473413 = 31473610
251 + 31473359 = 31473610
347 + 31473263 = 31473610

Showing the first eight; more decompositions exist.
