Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672558, here are decompositions:

7 + 8672551 = 8672558
19 + 8672539 = 8672558
31 + 8672527 = 8672558
151 + 8672407 = 8672558
211 + 8672347 = 8672558
397 + 8672161 = 8672558
457 + 8672101 = 8672558
571 + 8671987 = 8672558

Showing the first eight; more decompositions exist.
