Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671382, here are decompositions:

19 + 8671363 = 8671382
43 + 8671339 = 8671382
61 + 8671321 = 8671382
151 + 8671231 = 8671382
163 + 8671219 = 8671382
283 + 8671099 = 8671382
331 + 8671051 = 8671382
373 + 8671009 = 8671382

Showing the first eight; more decompositions exist.
