Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27580, here are decompositions:

29 + 27551 = 27580
41 + 27539 = 27580
53 + 27527 = 27580
71 + 27509 = 27580
101 + 27479 = 27580
131 + 27449 = 27580
149 + 27431 = 27580
173 + 27407 = 27580

Showing the first eight; more decompositions exist.
