Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602840, here are decompositions:

3 + 8602837 = 8602840
17 + 8602823 = 8602840
23 + 8602817 = 8602840
53 + 8602787 = 8602840
83 + 8602757 = 8602840
89 + 8602751 = 8602840
137 + 8602703 = 8602840
149 + 8602691 = 8602840

Showing the first eight; more decompositions exist.
