Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642674, here are decompositions:

23 + 8642651 = 8642674
41 + 8642633 = 8642674
83 + 8642591 = 8642674
107 + 8642567 = 8642674
167 + 8642507 = 8642674
563 + 8642111 = 8642674
617 + 8642057 = 8642674
641 + 8642033 = 8642674

Showing the first eight; more decompositions exist.
