Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623172, here are decompositions:

31 + 8623141 = 8623172
139 + 8623033 = 8623172
199 + 8622973 = 8623172
331 + 8622841 = 8623172
379 + 8622793 = 8623172
409 + 8622763 = 8623172
643 + 8622529 = 8623172
661 + 8622511 = 8623172

Showing the first eight; more decompositions exist.
