Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51550, here are decompositions:

11 + 51539 = 51550
29 + 51521 = 51550
47 + 51503 = 51550
71 + 51479 = 51550
89 + 51461 = 51550
101 + 51449 = 51550
113 + 51437 = 51550
131 + 51419 = 51550

Showing the first eight; more decompositions exist.
