Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599972, here are decompositions:

5 + 8599967 = 8599972
11 + 8599961 = 8599972
149 + 8599823 = 8599972
179 + 8599793 = 8599972
281 + 8599691 = 8599972
383 + 8599589 = 8599972
389 + 8599583 = 8599972
419 + 8599553 = 8599972

Showing the first eight; more decompositions exist.
