Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671832, here are decompositions:

163 + 8671669 = 8671832
193 + 8671639 = 8671832
199 + 8671633 = 8671832
283 + 8671549 = 8671832
313 + 8671519 = 8671832
331 + 8671501 = 8671832
439 + 8671393 = 8671832
541 + 8671291 = 8671832

Showing the first eight; more decompositions exist.
