Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671432, here are decompositions:

5 + 8671427 = 8671432
23 + 8671409 = 8671432
71 + 8671361 = 8671432
101 + 8671331 = 8671432
239 + 8671193 = 8671432
281 + 8671151 = 8671432
401 + 8671031 = 8671432
443 + 8670989 = 8671432

Showing the first eight; more decompositions exist.
