Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670580, here are decompositions:

29 + 8670551 = 8670580
47 + 8670533 = 8670580
71 + 8670509 = 8670580
89 + 8670491 = 8670580
173 + 8670407 = 8670580
227 + 8670353 = 8670580
383 + 8670197 = 8670580
389 + 8670191 = 8670580

Showing the first eight; more decompositions exist.
