Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641718, here are decompositions:

67 + 8641651 = 8641718
97 + 8641621 = 8641718
199 + 8641519 = 8641718
367 + 8641351 = 8641718
409 + 8641309 = 8641718
487 + 8641231 = 8641718
571 + 8641147 = 8641718
751 + 8640967 = 8641718

Showing the first eight; more decompositions exist.
