Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678878, here are decompositions:

101 + 8678777 = 8678878
137 + 8678741 = 8678878
179 + 8678699 = 8678878
239 + 8678639 = 8678878
359 + 8678519 = 8678878
431 + 8678447 = 8678878
479 + 8678399 = 8678878
641 + 8678237 = 8678878

Showing the first eight; more decompositions exist.
