Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665822, here are decompositions:

5 + 8665817 = 8665822
23 + 8665799 = 8665822
173 + 8665649 = 8665822
239 + 8665583 = 8665822
251 + 8665571 = 8665822
281 + 8665541 = 8665822
353 + 8665469 = 8665822
449 + 8665373 = 8665822

Showing the first eight; more decompositions exist.
