Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133690, here are decompositions:

17 + 133673 = 133690
41 + 133649 = 133690
59 + 133631 = 133690
107 + 133583 = 133690
131 + 133559 = 133690
149 + 133541 = 133690
191 + 133499 = 133690
197 + 133493 = 133690

Showing the first eight; more decompositions exist.
