Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600990, here are decompositions:

19 + 8600971 = 8600990
31 + 8600959 = 8600990
43 + 8600947 = 8600990
67 + 8600923 = 8600990
109 + 8600881 = 8600990
271 + 8600719 = 8600990
313 + 8600677 = 8600990
397 + 8600593 = 8600990

Showing the first eight; more decompositions exist.
