Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712874, here are decompositions:

11 + 8712863 = 8712874
47 + 8712827 = 8712874
113 + 8712761 = 8712874
173 + 8712701 = 8712874
197 + 8712677 = 8712874
263 + 8712611 = 8712874
383 + 8712491 = 8712874
503 + 8712371 = 8712874

Showing the first eight; more decompositions exist.
