Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101690, here are decompositions:

37 + 101653 = 101690
79 + 101611 = 101690
109 + 101581 = 101690
157 + 101533 = 101690
163 + 101527 = 101690
223 + 101467 = 101690
241 + 101449 = 101690
271 + 101419 = 101690

Showing the first eight; more decompositions exist.
