Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658844, here are decompositions:

71 + 8658773 = 8658844
167 + 8658677 = 8658844
191 + 8658653 = 8658844
263 + 8658581 = 8658844
317 + 8658527 = 8658844
431 + 8658413 = 8658844
461 + 8658383 = 8658844
521 + 8658323 = 8658844

Showing the first eight; more decompositions exist.
