Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105624, here are decompositions:

5 + 105619 = 105624
11 + 105613 = 105624
17 + 105607 = 105624
23 + 105601 = 105624
61 + 105563 = 105624
67 + 105557 = 105624
83 + 105541 = 105624
97 + 105527 = 105624

Showing the first eight; more decompositions exist.
