Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671990, here are decompositions:

3 + 8671987 = 8671990
11 + 8671979 = 8671990
23 + 8671967 = 8671990
53 + 8671937 = 8671990
71 + 8671919 = 8671990
83 + 8671907 = 8671990
179 + 8671811 = 8671990
251 + 8671739 = 8671990

Showing the first eight; more decompositions exist.
