Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645722, here are decompositions:

3 + 8645719 = 8645722
53 + 8645669 = 8645722
89 + 8645633 = 8645722
179 + 8645543 = 8645722
461 + 8645261 = 8645722
479 + 8645243 = 8645722
599 + 8645123 = 8645722
641 + 8645081 = 8645722

Showing the first eight; more decompositions exist.
