Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105382, here are decompositions:

3 + 105379 = 105382
23 + 105359 = 105382
41 + 105341 = 105382
59 + 105323 = 105382
113 + 105269 = 105382
131 + 105251 = 105382
239 + 105143 = 105382
311 + 105071 = 105382

Showing the first eight; more decompositions exist.
