Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658878, here are decompositions:

31 + 8658847 = 8658878
139 + 8658739 = 8658878
181 + 8658697 = 8658878
199 + 8658679 = 8658878
307 + 8658571 = 8658878
409 + 8658469 = 8658878
601 + 8658277 = 8658878
661 + 8658217 = 8658878

Showing the first eight; more decompositions exist.
