Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678018, here are decompositions:

7 + 8678011 = 8678018
67 + 8677951 = 8678018
127 + 8677891 = 8678018
337 + 8677681 = 8678018
367 + 8677651 = 8678018
541 + 8677477 = 8678018
619 + 8677399 = 8678018
631 + 8677387 = 8678018

Showing the first eight; more decompositions exist.
