Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37828, here are decompositions:

17 + 37811 = 37828
29 + 37799 = 37828
47 + 37781 = 37828
137 + 37691 = 37828
179 + 37649 = 37828
239 + 37589 = 37828
257 + 37571 = 37828
281 + 37547 = 37828

Showing the first eight; more decompositions exist.
