Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603138, here are decompositions:

7 + 8603131 = 8603138
97 + 8603041 = 8603138
151 + 8602987 = 8603138
331 + 8602807 = 8603138
409 + 8602729 = 8603138
571 + 8602567 = 8603138
619 + 8602519 = 8603138
631 + 8602507 = 8603138

Showing the first eight; more decompositions exist.
