Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664878, here are decompositions:

7 + 8664871 = 8664878
31 + 8664847 = 8664878
139 + 8664739 = 8664878
331 + 8664547 = 8664878
349 + 8664529 = 8664878
457 + 8664421 = 8664878
619 + 8664259 = 8664878
769 + 8664109 = 8664878

Showing the first eight; more decompositions exist.
