Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105540, here are decompositions:

7 + 105533 = 105540
11 + 105529 = 105540
13 + 105527 = 105540
23 + 105517 = 105540
31 + 105509 = 105540
37 + 105503 = 105540
41 + 105499 = 105540
73 + 105467 = 105540

Showing the first eight; more decompositions exist.
