Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105732, here are decompositions:

5 + 105727 = 105732
31 + 105701 = 105732
41 + 105691 = 105732
59 + 105673 = 105732
79 + 105653 = 105732
83 + 105649 = 105732
113 + 105619 = 105732
131 + 105601 = 105732

Showing the first eight; more decompositions exist.
