Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645792, here are decompositions:

3 + 8645789 = 8645792
19 + 8645773 = 8645792
31 + 8645761 = 8645792
73 + 8645719 = 8645792
139 + 8645653 = 8645792
349 + 8645443 = 8645792
433 + 8645359 = 8645792
439 + 8645353 = 8645792

Showing the first eight; more decompositions exist.
