Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658944, here are decompositions:

3 + 8658941 = 8658944
13 + 8658931 = 8658944
67 + 8658877 = 8658944
97 + 8658847 = 8658944
271 + 8658673 = 8658944
331 + 8658613 = 8658944
367 + 8658577 = 8658944
373 + 8658571 = 8658944

Showing the first eight; more decompositions exist.
