Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671424, here are decompositions:

31 + 8671393 = 8671424
43 + 8671381 = 8671424
61 + 8671363 = 8671424
103 + 8671321 = 8671424
193 + 8671231 = 8671424
277 + 8671147 = 8671424
367 + 8671057 = 8671424
373 + 8671051 = 8671424

Showing the first eight; more decompositions exist.
