Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645692, here are decompositions:

5 + 8645687 = 8645692
23 + 8645669 = 8645692
59 + 8645633 = 8645692
113 + 8645579 = 8645692
149 + 8645543 = 8645692
311 + 8645381 = 8645692
431 + 8645261 = 8645692
449 + 8645243 = 8645692

Showing the first eight; more decompositions exist.
