Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621474, here are decompositions:

7 + 8621467 = 8621474
31 + 8621443 = 8621474
61 + 8621413 = 8621474
97 + 8621377 = 8621474
193 + 8621281 = 8621474
331 + 8621143 = 8621474
373 + 8621101 = 8621474
397 + 8621077 = 8621474

Showing the first eight; more decompositions exist.
