Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749918, here are decompositions:

71 + 8749847 = 8749918
101 + 8749817 = 8749918
131 + 8749787 = 8749918
167 + 8749751 = 8749918
311 + 8749607 = 8749918
347 + 8749571 = 8749918
449 + 8749469 = 8749918
461 + 8749457 = 8749918

Showing the first eight; more decompositions exist.
