Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473646, here are decompositions:

47 + 31473599 = 31473646
53 + 31473593 = 31473646
167 + 31473479 = 31473646
233 + 31473413 = 31473646
383 + 31473263 = 31473646
443 + 31473203 = 31473646
563 + 31473083 = 31473646
569 + 31473077 = 31473646

Showing the first eight; more decompositions exist.
