Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647742, here are decompositions:

3 + 8647739 = 8647742
31 + 8647711 = 8647742
43 + 8647699 = 8647742
163 + 8647579 = 8647742
211 + 8647531 = 8647742
241 + 8647501 = 8647742
283 + 8647459 = 8647742
331 + 8647411 = 8647742

Showing the first eight; more decompositions exist.
