Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105650, here are decompositions:

31 + 105619 = 105650
37 + 105613 = 105650
43 + 105607 = 105650
109 + 105541 = 105650
151 + 105499 = 105650
271 + 105379 = 105650
277 + 105373 = 105650
283 + 105367 = 105650

Showing the first eight; more decompositions exist.
