Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671988, here are decompositions:

7 + 8671981 = 8671988
151 + 8671837 = 8671988
277 + 8671711 = 8671988
349 + 8671639 = 8671988
439 + 8671549 = 8671988
487 + 8671501 = 8671988
541 + 8671447 = 8671988
547 + 8671441 = 8671988

Showing the first eight; more decompositions exist.
