Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626580, here are decompositions:

3 + 8626577 = 8626580
31 + 8626549 = 8626580
73 + 8626507 = 8626580
163 + 8626417 = 8626580
283 + 8626297 = 8626580
331 + 8626249 = 8626580
337 + 8626243 = 8626580
421 + 8626159 = 8626580

Showing the first eight; more decompositions exist.
