Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105508, here are decompositions:

5 + 105503 = 105508
17 + 105491 = 105508
41 + 105467 = 105508
59 + 105449 = 105508
71 + 105437 = 105508
101 + 105407 = 105508
107 + 105401 = 105508
149 + 105359 = 105508

Showing the first eight; more decompositions exist.
