Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724792, here are decompositions:

5 + 8724787 = 8724792
53 + 8724739 = 8724792
71 + 8724721 = 8724792
73 + 8724719 = 8724792
79 + 8724713 = 8724792
149 + 8724643 = 8724792
151 + 8724641 = 8724792
173 + 8724619 = 8724792

Showing the first eight; more decompositions exist.
