Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712978, here are decompositions:

5 + 8712973 = 8712978
47 + 8712931 = 8712978
59 + 8712919 = 8712978
151 + 8712827 = 8712978
199 + 8712779 = 8712978
227 + 8712751 = 8712978
229 + 8712749 = 8712978
251 + 8712727 = 8712978

Showing the first eight; more decompositions exist.
