Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101786, here are decompositions:

37 + 101749 = 101786
67 + 101719 = 101786
283 + 101503 = 101786
337 + 101449 = 101786
367 + 101419 = 101786
409 + 101377 = 101786
439 + 101347 = 101786
463 + 101323 = 101786

Showing the first eight; more decompositions exist.
