Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728718, here are decompositions:

7 + 8728711 = 8728718
109 + 8728609 = 8728718
127 + 8728591 = 8728718
139 + 8728579 = 8728718
331 + 8728387 = 8728718
337 + 8728381 = 8728718
409 + 8728309 = 8728718
457 + 8728261 = 8728718

Showing the first eight; more decompositions exist.
