Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747826, here are decompositions:

7 + 8747819 = 8747826
19 + 8747807 = 8747826
23 + 8747803 = 8747826
37 + 8747789 = 8747826
67 + 8747759 = 8747826
79 + 8747747 = 8747826
83 + 8747743 = 8747826
89 + 8747737 = 8747826

Showing the first eight; more decompositions exist.
