Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671446, here are decompositions:

5 + 8671441 = 8671446
19 + 8671427 = 8671446
37 + 8671409 = 8671446
53 + 8671393 = 8671446
79 + 8671367 = 8671446
83 + 8671363 = 8671446
107 + 8671339 = 8671446
139 + 8671307 = 8671446

Showing the first eight; more decompositions exist.
