Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731508, here are decompositions:

7 + 8731501 = 8731508
31 + 8731477 = 8731508
61 + 8731447 = 8731508
127 + 8731381 = 8731508
139 + 8731369 = 8731508
199 + 8731309 = 8731508
277 + 8731231 = 8731508
307 + 8731201 = 8731508

Showing the first eight; more decompositions exist.
