Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665654, here are decompositions:

3 + 8665651 = 8665654
5 + 8665649 = 8665654
71 + 8665583 = 8665654
83 + 8665571 = 8665654
113 + 8665541 = 8665654
281 + 8665373 = 8665654
293 + 8665361 = 8665654
401 + 8665253 = 8665654

Showing the first eight; more decompositions exist.
