Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621674, here are decompositions:

197 + 8621477 = 8621674
263 + 8621411 = 8621674
431 + 8621243 = 8621674
461 + 8621213 = 8621674
491 + 8621183 = 8621674
521 + 8621153 = 8621674
587 + 8621087 = 8621674
701 + 8620973 = 8621674

Showing the first eight; more decompositions exist.
