Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671946, here are decompositions:

109 + 8671837 = 8671946
277 + 8671669 = 8671946
307 + 8671639 = 8671946
313 + 8671633 = 8671946
373 + 8671573 = 8671946
397 + 8671549 = 8671946
499 + 8671447 = 8671946
607 + 8671339 = 8671946

Showing the first eight; more decompositions exist.
