Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642678, here are decompositions:

97 + 8642581 = 8642678
211 + 8642467 = 8642678
229 + 8642449 = 8642678
349 + 8642329 = 8642678
397 + 8642281 = 8642678
571 + 8642107 = 8642678
601 + 8642077 = 8642678
619 + 8642059 = 8642678

Showing the first eight; more decompositions exist.
