Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83858, here are decompositions:

67 + 83791 = 83858
97 + 83761 = 83858
139 + 83719 = 83858
157 + 83701 = 83858
241 + 83617 = 83858
409 + 83449 = 83858
421 + 83437 = 83858
457 + 83401 = 83858

Showing the first eight; more decompositions exist.
