Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599728, here are decompositions:

37 + 8599691 = 8599728
41 + 8599687 = 8599728
61 + 8599667 = 8599728
79 + 8599649 = 8599728
139 + 8599589 = 8599728
149 + 8599579 = 8599728
167 + 8599561 = 8599728
239 + 8599489 = 8599728

Showing the first eight; more decompositions exist.
