Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719912, here are decompositions:

251 + 8719661 = 8719912
491 + 8719421 = 8719912
521 + 8719391 = 8719912
563 + 8719349 = 8719912
659 + 8719253 = 8719912
701 + 8719211 = 8719912
863 + 8719049 = 8719912
881 + 8719031 = 8719912

Showing the first eight; more decompositions exist.
