Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671930, here are decompositions:

11 + 8671919 = 8671930
23 + 8671907 = 8671930
191 + 8671739 = 8671930
233 + 8671697 = 8671930
347 + 8671583 = 8671930
419 + 8671511 = 8671930
431 + 8671499 = 8671930
461 + 8671469 = 8671930

Showing the first eight; more decompositions exist.
