Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671826, here are decompositions:

157 + 8671669 = 8671826
193 + 8671633 = 8671826
277 + 8671549 = 8671826
307 + 8671519 = 8671826
379 + 8671447 = 8671826
433 + 8671393 = 8671826
463 + 8671363 = 8671826
487 + 8671339 = 8671826

Showing the first eight; more decompositions exist.
