Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726744, here are decompositions:

7 + 8726737 = 8726744
31 + 8726713 = 8726744
67 + 8726677 = 8726744
73 + 8726671 = 8726744
97 + 8726647 = 8726744
157 + 8726587 = 8726744
211 + 8726533 = 8726744
223 + 8726521 = 8726744

Showing the first eight; more decompositions exist.
