Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618770, here are decompositions:

11 + 8618759 = 8618770
23 + 8618747 = 8618770
71 + 8618699 = 8618770
89 + 8618681 = 8618770
131 + 8618639 = 8618770
179 + 8618591 = 8618770
269 + 8618501 = 8618770
383 + 8618387 = 8618770

Showing the first eight; more decompositions exist.
