Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617642, here are decompositions:

251 + 8617391 = 8617642
269 + 8617373 = 8617642
281 + 8617361 = 8617642
389 + 8617253 = 8617642
431 + 8617211 = 8617642
569 + 8617073 = 8617642
641 + 8617001 = 8617642
653 + 8616989 = 8617642

Showing the first eight; more decompositions exist.
