Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105778, here are decompositions:

11 + 105767 = 105778
17 + 105761 = 105778
251 + 105527 = 105778
269 + 105509 = 105778
311 + 105467 = 105778
389 + 105389 = 105778
419 + 105359 = 105778
509 + 105269 = 105778

Showing the first eight; more decompositions exist.
