Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103786, here are decompositions:

17 + 103769 = 103786
83 + 103703 = 103786
167 + 103619 = 103786
173 + 103613 = 103786
233 + 103553 = 103786
257 + 103529 = 103786
467 + 103319 = 103786
479 + 103307 = 103786

Showing the first eight; more decompositions exist.
