Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671630, here are decompositions:

41 + 8671589 = 8671630
47 + 8671583 = 8671630
113 + 8671517 = 8671630
131 + 8671499 = 8671630
167 + 8671463 = 8671630
173 + 8671457 = 8671630
263 + 8671367 = 8671630
269 + 8671361 = 8671630

Showing the first eight; more decompositions exist.
