Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719626, here are decompositions:

23 + 8719603 = 8719626
53 + 8719573 = 8719626
59 + 8719567 = 8719626
107 + 8719519 = 8719626
277 + 8719349 = 8719626
337 + 8719289 = 8719626
353 + 8719273 = 8719626
373 + 8719253 = 8719626

Showing the first eight; more decompositions exist.
