Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621962, here are decompositions:

3 + 8621959 = 8621962
23 + 8621939 = 8621962
29 + 8621933 = 8621962
101 + 8621861 = 8621962
131 + 8621831 = 8621962
269 + 8621693 = 8621962
281 + 8621681 = 8621962
353 + 8621609 = 8621962

Showing the first eight; more decompositions exist.
