Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647792, here are decompositions:

53 + 8647739 = 8647792
281 + 8647511 = 8647792
383 + 8647409 = 8647792
401 + 8647391 = 8647792
443 + 8647349 = 8647792
563 + 8647229 = 8647792
599 + 8647193 = 8647792
653 + 8647139 = 8647792

Showing the first eight; more decompositions exist.
