Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618764, here are decompositions:

5 + 8618759 = 8618764
17 + 8618747 = 8618764
83 + 8618681 = 8618764
173 + 8618591 = 8618764
197 + 8618567 = 8618764
263 + 8618501 = 8618764
281 + 8618483 = 8618764
467 + 8618297 = 8618764

Showing the first eight; more decompositions exist.
