Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670978, here are decompositions:

31 + 8670947 = 8670978
37 + 8670941 = 8670978
59 + 8670919 = 8670978
109 + 8670869 = 8670978
167 + 8670811 = 8670978
227 + 8670751 = 8670978
269 + 8670709 = 8670978
311 + 8670667 = 8670978

Showing the first eight; more decompositions exist.
