Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739378, here are decompositions:

19 + 8739359 = 8739378
29 + 8739349 = 8739378
41 + 8739337 = 8739378
47 + 8739331 = 8739378
79 + 8739299 = 8739378
97 + 8739281 = 8739378
181 + 8739197 = 8739378
191 + 8739187 = 8739378

Showing the first eight; more decompositions exist.
