Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702678, here are decompositions:

31 + 8702647 = 8702678
109 + 8702569 = 8702678
139 + 8702539 = 8702678
181 + 8702497 = 8702678
307 + 8702371 = 8702678
337 + 8702341 = 8702678
349 + 8702329 = 8702678
367 + 8702311 = 8702678

Showing the first eight; more decompositions exist.
