Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671884, here are decompositions:

47 + 8671837 = 8671884
73 + 8671811 = 8671884
163 + 8671721 = 8671884
173 + 8671711 = 8671884
251 + 8671633 = 8671884
311 + 8671573 = 8671884
367 + 8671517 = 8671884
373 + 8671511 = 8671884

Showing the first eight; more decompositions exist.
