Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473712, here are decompositions:

5 + 31473707 = 31473712
113 + 31473599 = 31473712
131 + 31473581 = 31473712
233 + 31473479 = 31473712
353 + 31473359 = 31473712
449 + 31473263 = 31473712
461 + 31473251 = 31473712
503 + 31473209 = 31473712

Showing the first eight; more decompositions exist.
