Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740644, here are decompositions:

37 + 8740607 = 8740644
41 + 8740603 = 8740644
53 + 8740591 = 8740644
67 + 8740577 = 8740644
83 + 8740561 = 8740644
103 + 8740541 = 8740644
113 + 8740531 = 8740644
127 + 8740517 = 8740644

Showing the first eight; more decompositions exist.
