Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51582, here are decompositions:

5 + 51577 = 51582
19 + 51563 = 51582
31 + 51551 = 51582
43 + 51539 = 51582
61 + 51521 = 51582
71 + 51511 = 51582
79 + 51503 = 51582
101 + 51481 = 51582

Showing the first eight; more decompositions exist.
