Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640698, here are decompositions:

7 + 8640691 = 8640698
19 + 8640679 = 8640698
97 + 8640601 = 8640698
139 + 8640559 = 8640698
151 + 8640547 = 8640698
271 + 8640427 = 8640698
307 + 8640391 = 8640698
349 + 8640349 = 8640698

Showing the first eight; more decompositions exist.
