Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599990, here are decompositions:

23 + 8599967 = 8599990
29 + 8599961 = 8599990
167 + 8599823 = 8599990
173 + 8599817 = 8599990
197 + 8599793 = 8599990
317 + 8599673 = 8599990
383 + 8599607 = 8599990
401 + 8599589 = 8599990

Showing the first eight; more decompositions exist.
