Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731118, here are decompositions:

7 + 8731111 = 8731118
79 + 8731039 = 8731118
199 + 8730919 = 8731118
229 + 8730889 = 8731118
271 + 8730847 = 8731118
337 + 8730781 = 8731118
421 + 8730697 = 8731118
457 + 8730661 = 8731118

Showing the first eight; more decompositions exist.
