Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665222, here are decompositions:

3 + 8665219 = 8665222
29 + 8665193 = 8665222
113 + 8665109 = 8665222
149 + 8665073 = 8665222
191 + 8665031 = 8665222
263 + 8664959 = 8665222
281 + 8664941 = 8665222
353 + 8664869 = 8665222

Showing the first eight; more decompositions exist.
