Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665612, here are decompositions:

29 + 8665583 = 8665612
41 + 8665571 = 8665612
71 + 8665541 = 8665612
113 + 8665499 = 8665612
239 + 8665373 = 8665612
251 + 8665361 = 8665612
353 + 8665259 = 8665612
359 + 8665253 = 8665612

Showing the first eight; more decompositions exist.
