Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604638, here are decompositions:

109 + 8604529 = 8604638
151 + 8604487 = 8604638
157 + 8604481 = 8604638
331 + 8604307 = 8604638
379 + 8604259 = 8604638
397 + 8604241 = 8604638
487 + 8604151 = 8604638
571 + 8604067 = 8604638

Showing the first eight; more decompositions exist.
