Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105588, here are decompositions:

31 + 105557 = 105588
47 + 105541 = 105588
59 + 105529 = 105588
61 + 105527 = 105588
71 + 105517 = 105588
79 + 105509 = 105588
89 + 105499 = 105588
97 + 105491 = 105588

Showing the first eight; more decompositions exist.
