Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643696, here are decompositions:

23 + 8643673 = 8643696
107 + 8643589 = 8643696
109 + 8643587 = 8643696
157 + 8643539 = 8643696
239 + 8643457 = 8643696
263 + 8643433 = 8643696
337 + 8643359 = 8643696
353 + 8643343 = 8643696

Showing the first eight; more decompositions exist.
