Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599642, here are decompositions:

53 + 8599589 = 8599642
59 + 8599583 = 8599642
83 + 8599559 = 8599642
89 + 8599553 = 8599642
101 + 8599541 = 8599642
173 + 8599469 = 8599642
239 + 8599403 = 8599642
263 + 8599379 = 8599642

Showing the first eight; more decompositions exist.
