Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659438, here are decompositions:

149 + 8659289 = 8659438
257 + 8659181 = 8659438
317 + 8659121 = 8659438
401 + 8659037 = 8659438
419 + 8659019 = 8659438
449 + 8658989 = 8659438
461 + 8658977 = 8659438
479 + 8658959 = 8659438

Showing the first eight; more decompositions exist.
