Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689718, here are decompositions:

7 + 8689711 = 8689718
31 + 8689687 = 8689718
61 + 8689657 = 8689718
109 + 8689609 = 8689718
127 + 8689591 = 8689718
181 + 8689537 = 8689718
229 + 8689489 = 8689718
397 + 8689321 = 8689718

Showing the first eight; more decompositions exist.
