Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670530, here are decompositions:

7 + 8670523 = 8670530
31 + 8670499 = 8670530
79 + 8670451 = 8670530
97 + 8670433 = 8670530
157 + 8670373 = 8670530
199 + 8670331 = 8670530
229 + 8670301 = 8670530
373 + 8670157 = 8670530

Showing the first eight; more decompositions exist.
