Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105598, here are decompositions:

41 + 105557 = 105598
71 + 105527 = 105598
89 + 105509 = 105598
107 + 105491 = 105598
131 + 105467 = 105598
149 + 105449 = 105598
191 + 105407 = 105598
197 + 105401 = 105598

Showing the first eight; more decompositions exist.
