Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645426, here are decompositions:

19 + 8645407 = 8645426
67 + 8645359 = 8645426
73 + 8645353 = 8645426
157 + 8645269 = 8645426
313 + 8645113 = 8645426
373 + 8645053 = 8645426
379 + 8645047 = 8645426
397 + 8645029 = 8645426

Showing the first eight; more decompositions exist.
