Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61540, here are decompositions:

29 + 61511 = 61540
47 + 61493 = 61540
53 + 61487 = 61540
71 + 61469 = 61540
131 + 61409 = 61540
137 + 61403 = 61540
197 + 61343 = 61540
257 + 61283 = 61540

Showing the first eight; more decompositions exist.
