Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659842, here are decompositions:

5 + 8659837 = 8659842
31 + 8659811 = 8659842
73 + 8659769 = 8659842
101 + 8659741 = 8659842
131 + 8659711 = 8659842
151 + 8659691 = 8659842
173 + 8659669 = 8659842
179 + 8659663 = 8659842

Showing the first eight; more decompositions exist.
