Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37858, here are decompositions:

5 + 37853 = 37858
11 + 37847 = 37858
47 + 37811 = 37858
59 + 37799 = 37858
167 + 37691 = 37858
239 + 37619 = 37858
251 + 37607 = 37858
269 + 37589 = 37858

Showing the first eight; more decompositions exist.
