Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659542, here are decompositions:

5 + 8659537 = 8659542
11 + 8659531 = 8659542
29 + 8659513 = 8659542
41 + 8659501 = 8659542
71 + 8659471 = 8659542
79 + 8659463 = 8659542
149 + 8659393 = 8659542
179 + 8659363 = 8659542

Showing the first eight; more decompositions exist.
