Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109782, here are decompositions:

31 + 109751 = 109782
41 + 109741 = 109782
61 + 109721 = 109782
109 + 109673 = 109782
163 + 109619 = 109782
173 + 109609 = 109782
193 + 109589 = 109782
199 + 109583 = 109782

Showing the first eight; more decompositions exist.
