Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726906, here are decompositions:

43 + 8726863 = 8726906
103 + 8726803 = 8726906
193 + 8726713 = 8726906
229 + 8726677 = 8726906
337 + 8726569 = 8726906
373 + 8726533 = 8726906
379 + 8726527 = 8726906
439 + 8726467 = 8726906

Showing the first eight; more decompositions exist.
