Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609742, here are decompositions:

13 + 8609729 = 8609742
23 + 8609719 = 8609742
59 + 8609683 = 8609742
73 + 8609669 = 8609742
79 + 8609663 = 8609742
103 + 8609639 = 8609742
131 + 8609611 = 8609742
151 + 8609591 = 8609742

Showing the first eight; more decompositions exist.
