Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603978, here are decompositions:

139 + 8603839 = 8603978
181 + 8603797 = 8603978
199 + 8603779 = 8603978
211 + 8603767 = 8603978
277 + 8603701 = 8603978
367 + 8603611 = 8603978
457 + 8603521 = 8603978
571 + 8603407 = 8603978

Showing the first eight; more decompositions exist.
