Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739278, here are decompositions:

109 + 8739169 = 8739278
151 + 8739127 = 8739278
181 + 8739097 = 8739278
199 + 8739079 = 8739278
271 + 8739007 = 8739278
277 + 8739001 = 8739278
349 + 8738929 = 8739278
397 + 8738881 = 8739278

Showing the first eight; more decompositions exist.
