Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718580, here are decompositions:

41 + 8718539 = 8718580
89 + 8718491 = 8718580
149 + 8718431 = 8718580
173 + 8718407 = 8718580
179 + 8718401 = 8718580
359 + 8718221 = 8718580
383 + 8718197 = 8718580
389 + 8718191 = 8718580

Showing the first eight; more decompositions exist.
