Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641692, here are decompositions:

19 + 8641673 = 8641692
23 + 8641669 = 8641692
41 + 8641651 = 8641692
61 + 8641631 = 8641692
71 + 8641621 = 8641692
79 + 8641613 = 8641692
89 + 8641603 = 8641692
149 + 8641543 = 8641692

Showing the first eight; more decompositions exist.
