Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641730, here are decompositions:

61 + 8641669 = 8641730
79 + 8641651 = 8641730
109 + 8641621 = 8641730
127 + 8641603 = 8641730
211 + 8641519 = 8641730
277 + 8641453 = 8641730
379 + 8641351 = 8641730
421 + 8641309 = 8641730

Showing the first eight; more decompositions exist.
