Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12550, here are decompositions:

3 + 12547 = 12550
11 + 12539 = 12550
23 + 12527 = 12550
47 + 12503 = 12550
53 + 12497 = 12550
59 + 12491 = 12550
71 + 12479 = 12550
113 + 12437 = 12550

Showing the first eight; more decompositions exist.
