Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600890, here are decompositions:

71 + 8600819 = 8600890
83 + 8600807 = 8600890
101 + 8600789 = 8600890
107 + 8600783 = 8600890
113 + 8600777 = 8600890
149 + 8600741 = 8600890
173 + 8600717 = 8600890
251 + 8600639 = 8600890

Showing the first eight; more decompositions exist.
