Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659402, here are decompositions:

113 + 8659289 = 8659402
179 + 8659223 = 8659402
281 + 8659121 = 8659402
359 + 8659043 = 8659402
383 + 8659019 = 8659402
419 + 8658983 = 8659402
443 + 8658959 = 8659402
461 + 8658941 = 8659402

Showing the first eight; more decompositions exist.
