Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100786, here are decompositions:

17 + 100769 = 100786
53 + 100733 = 100786
83 + 100703 = 100786
113 + 100673 = 100786
137 + 100649 = 100786
173 + 100613 = 100786
227 + 100559 = 100786
239 + 100547 = 100786

Showing the first eight; more decompositions exist.
