Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51558, here are decompositions:

7 + 51551 = 51558
19 + 51539 = 51558
37 + 51521 = 51558
41 + 51517 = 51558
47 + 51511 = 51558
71 + 51487 = 51558
79 + 51479 = 51558
97 + 51461 = 51558

Showing the first eight; more decompositions exist.
