Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738978, here are decompositions:

97 + 8738881 = 8738978
139 + 8738839 = 8738978
211 + 8738767 = 8738978
271 + 8738707 = 8738978
307 + 8738671 = 8738978
337 + 8738641 = 8738978
397 + 8738581 = 8738978
439 + 8738539 = 8738978

Showing the first eight; more decompositions exist.
