Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665804, here are decompositions:

5 + 8665799 = 8665804
101 + 8665703 = 8665804
137 + 8665667 = 8665804
233 + 8665571 = 8665804
263 + 8665541 = 8665804
353 + 8665451 = 8665804
431 + 8665373 = 8665804
443 + 8665361 = 8665804

Showing the first eight; more decompositions exist.
