Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702978, here are decompositions:

19 + 8702959 = 8702978
139 + 8702839 = 8702978
157 + 8702821 = 8702978
331 + 8702647 = 8702978
409 + 8702569 = 8702978
421 + 8702557 = 8702978
439 + 8702539 = 8702978
547 + 8702431 = 8702978

Showing the first eight; more decompositions exist.
