Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731616, here are decompositions:

7 + 8731609 = 8731616
37 + 8731579 = 8731616
139 + 8731477 = 8731616
199 + 8731417 = 8731616
277 + 8731339 = 8731616
307 + 8731309 = 8731616
367 + 8731249 = 8731616
463 + 8731153 = 8731616

Showing the first eight; more decompositions exist.
