Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51580, here are decompositions:

3 + 51577 = 51580
17 + 51563 = 51580
29 + 51551 = 51580
41 + 51539 = 51580
59 + 51521 = 51580
101 + 51479 = 51580
107 + 51473 = 51580
131 + 51449 = 51580

Showing the first eight; more decompositions exist.
