Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749966, here are decompositions:

149 + 8749817 = 8749966
179 + 8749787 = 8749966
233 + 8749733 = 8749966
353 + 8749613 = 8749966
359 + 8749607 = 8749966
509 + 8749457 = 8749966
839 + 8749127 = 8749966
947 + 8749019 = 8749966

Showing the first eight; more decompositions exist.
