Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645764, here are decompositions:

3 + 8645761 = 8645764
5 + 8645759 = 8645764
107 + 8645657 = 8645764
131 + 8645633 = 8645764
167 + 8645597 = 8645764
383 + 8645381 = 8645764
503 + 8645261 = 8645764
521 + 8645243 = 8645764

Showing the first eight; more decompositions exist.
