Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678818, here are decompositions:

41 + 8678777 = 8678818
59 + 8678759 = 8678818
149 + 8678669 = 8678818
179 + 8678639 = 8678818
311 + 8678507 = 8678818
419 + 8678399 = 8678818
479 + 8678339 = 8678818
677 + 8678141 = 8678818

Showing the first eight; more decompositions exist.
