Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473586, here are decompositions:

3 + 31473583 = 31473586
5 + 31473581 = 31473586
107 + 31473479 = 31473586
149 + 31473437 = 31473586
173 + 31473413 = 31473586
227 + 31473359 = 31473586
383 + 31473203 = 31473586
479 + 31473107 = 31473586

Showing the first eight; more decompositions exist.
