Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671582, here are decompositions:

71 + 8671511 = 8671582
83 + 8671499 = 8671582
113 + 8671469 = 8671582
173 + 8671409 = 8671582
251 + 8671331 = 8671582
389 + 8671193 = 8671582
431 + 8671151 = 8671582
449 + 8671133 = 8671582

Showing the first eight; more decompositions exist.
