Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648722, here are decompositions:

179 + 8648543 = 8648722
191 + 8648531 = 8648722
263 + 8648459 = 8648722
353 + 8648369 = 8648722
389 + 8648333 = 8648722
743 + 8647979 = 8648722
773 + 8647949 = 8648722
809 + 8647913 = 8648722

Showing the first eight; more decompositions exist.
