Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105580, here are decompositions:

17 + 105563 = 105580
23 + 105557 = 105580
47 + 105533 = 105580
53 + 105527 = 105580
71 + 105509 = 105580
89 + 105491 = 105580
113 + 105467 = 105580
131 + 105449 = 105580

Showing the first eight; more decompositions exist.
