Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13750, here are decompositions:

29 + 13721 = 13750
41 + 13709 = 13750
53 + 13697 = 13750
59 + 13691 = 13750
71 + 13679 = 13750
101 + 13649 = 13750
131 + 13619 = 13750
137 + 13613 = 13750

Showing the first eight; more decompositions exist.
