Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61500, here are decompositions:

7 + 61493 = 61500
13 + 61487 = 61500
17 + 61483 = 61500
29 + 61471 = 61500
31 + 61469 = 61500
37 + 61463 = 61500
59 + 61441 = 61500
83 + 61417 = 61500

Showing the first eight; more decompositions exist.
