Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101066, here are decompositions:

3 + 101063 = 101066
67 + 100999 = 101066
79 + 100987 = 101066
109 + 100957 = 101066
139 + 100927 = 101066
367 + 100699 = 101066
373 + 100693 = 101066
397 + 100669 = 101066

Showing the first eight; more decompositions exist.
