Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642694, here are decompositions:

43 + 8642651 = 8642694
61 + 8642633 = 8642694
103 + 8642591 = 8642694
113 + 8642581 = 8642694
127 + 8642567 = 8642694
227 + 8642467 = 8642694
241 + 8642453 = 8642694
311 + 8642383 = 8642694

Showing the first eight; more decompositions exist.
