Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678742, here are decompositions:

29 + 8678713 = 8678742
41 + 8678701 = 8678742
43 + 8678699 = 8678742
71 + 8678671 = 8678742
73 + 8678669 = 8678742
103 + 8678639 = 8678742
139 + 8678603 = 8678742
223 + 8678519 = 8678742

Showing the first eight; more decompositions exist.
