Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42500, here are decompositions:

13 + 42487 = 42500
37 + 42463 = 42500
43 + 42457 = 42500
67 + 42433 = 42500
97 + 42403 = 42500
103 + 42397 = 42500
109 + 42391 = 42500
127 + 42373 = 42500

Showing the first eight; more decompositions exist.
