Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741978, here are decompositions:

31 + 8741947 = 8741978
67 + 8741911 = 8741978
139 + 8741839 = 8741978
181 + 8741797 = 8741978
199 + 8741779 = 8741978
229 + 8741749 = 8741978
337 + 8741641 = 8741978
457 + 8741521 = 8741978

Showing the first eight; more decompositions exist.
