Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728946, here are decompositions:

3 + 8728943 = 8728946
19 + 8728927 = 8728946
43 + 8728903 = 8728946
97 + 8728849 = 8728946
139 + 8728807 = 8728946
229 + 8728717 = 8728946
283 + 8728663 = 8728946
337 + 8728609 = 8728946

Showing the first eight; more decompositions exist.
