Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642792, here are decompositions:

19 + 8642773 = 8642792
31 + 8642761 = 8642792
211 + 8642581 = 8642792
283 + 8642509 = 8642792
409 + 8642383 = 8642792
463 + 8642329 = 8642792
619 + 8642173 = 8642792
673 + 8642119 = 8642792

Showing the first eight; more decompositions exist.
