Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105550, here are decompositions:

17 + 105533 = 105550
23 + 105527 = 105550
41 + 105509 = 105550
47 + 105503 = 105550
59 + 105491 = 105550
83 + 105467 = 105550
101 + 105449 = 105550
113 + 105437 = 105550

Showing the first eight; more decompositions exist.
