Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602990, here are decompositions:

3 + 8602987 = 8602990
29 + 8602961 = 8602990
41 + 8602949 = 8602990
59 + 8602931 = 8602990
167 + 8602823 = 8602990
173 + 8602817 = 8602990
233 + 8602757 = 8602990
239 + 8602751 = 8602990

Showing the first eight; more decompositions exist.
