Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739778, here are decompositions:

11 + 8739767 = 8739778
29 + 8739749 = 8739778
107 + 8739671 = 8739778
347 + 8739431 = 8739778
389 + 8739389 = 8739778
419 + 8739359 = 8739778
479 + 8739299 = 8739778
569 + 8739209 = 8739778

Showing the first eight; more decompositions exist.
