Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657906, here are decompositions:

3 + 8657903 = 8657906
73 + 8657833 = 8657906
79 + 8657827 = 8657906
139 + 8657767 = 8657906
277 + 8657629 = 8657906
337 + 8657569 = 8657906
349 + 8657557 = 8657906
373 + 8657533 = 8657906

Showing the first eight; more decompositions exist.
