Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672018, here are decompositions:

31 + 8671987 = 8672018
37 + 8671981 = 8672018
181 + 8671837 = 8672018
307 + 8671711 = 8672018
349 + 8671669 = 8672018
379 + 8671639 = 8672018
499 + 8671519 = 8672018
547 + 8671471 = 8672018

Showing the first eight; more decompositions exist.
