Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12580, here are decompositions:

3 + 12577 = 12580
11 + 12569 = 12580
41 + 12539 = 12580
53 + 12527 = 12580
83 + 12497 = 12580
89 + 12491 = 12580
101 + 12479 = 12580
107 + 12473 = 12580

Showing the first eight; more decompositions exist.
