Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731712, here are decompositions:

13 + 8731699 = 8731712
103 + 8731609 = 8731712
181 + 8731531 = 8731712
211 + 8731501 = 8731712
331 + 8731381 = 8731712
349 + 8731363 = 8731712
373 + 8731339 = 8731712
463 + 8731249 = 8731712

Showing the first eight; more decompositions exist.
