Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642704, here are decompositions:

53 + 8642651 = 8642704
71 + 8642633 = 8642704
113 + 8642591 = 8642704
137 + 8642567 = 8642704
197 + 8642507 = 8642704
251 + 8642453 = 8642704
401 + 8642303 = 8642704
467 + 8642237 = 8642704

Showing the first eight; more decompositions exist.
