Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665212, here are decompositions:

5 + 8665207 = 8665212
11 + 8665201 = 8665212
19 + 8665193 = 8665212
89 + 8665123 = 8665212
103 + 8665109 = 8665212
113 + 8665099 = 8665212
139 + 8665073 = 8665212
173 + 8665039 = 8665212

Showing the first eight; more decompositions exist.
