Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473616, here are decompositions:

17 + 31473599 = 31473616
23 + 31473593 = 31473616
137 + 31473479 = 31473616
179 + 31473437 = 31473616
257 + 31473359 = 31473616
353 + 31473263 = 31473616
443 + 31473173 = 31473616
509 + 31473107 = 31473616

Showing the first eight; more decompositions exist.
