Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665508, here are decompositions:

37 + 8665471 = 8665508
67 + 8665441 = 8665508
79 + 8665429 = 8665508
139 + 8665369 = 8665508
151 + 8665357 = 8665508
307 + 8665201 = 8665508
409 + 8665099 = 8665508
487 + 8665021 = 8665508

Showing the first eight; more decompositions exist.
