Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101566, here are decompositions:

5 + 101561 = 101566
29 + 101537 = 101566
53 + 101513 = 101566
83 + 101483 = 101566
89 + 101477 = 101566
137 + 101429 = 101566
167 + 101399 = 101566
233 + 101333 = 101566

Showing the first eight; more decompositions exist.
