Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732978, here are decompositions:

109 + 8732869 = 8732978
139 + 8732839 = 8732978
181 + 8732797 = 8732978
229 + 8732749 = 8732978
337 + 8732641 = 8732978
379 + 8732599 = 8732978
547 + 8732431 = 8732978
607 + 8732371 = 8732978

Showing the first eight; more decompositions exist.
