Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718622, here are decompositions:

41 + 8718581 = 8718622
83 + 8718539 = 8718622
131 + 8718491 = 8718622
191 + 8718431 = 8718622
401 + 8718221 = 8718622
431 + 8718191 = 8718622
509 + 8718113 = 8718622
641 + 8717981 = 8718622

Showing the first eight; more decompositions exist.
