Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731568, here are decompositions:

37 + 8731531 = 8731568
67 + 8731501 = 8731568
151 + 8731417 = 8731568
199 + 8731369 = 8731568
229 + 8731339 = 8731568
337 + 8731231 = 8731568
367 + 8731201 = 8731568
457 + 8731111 = 8731568

Showing the first eight; more decompositions exist.
