Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101906, here are decompositions:

37 + 101869 = 101906
43 + 101863 = 101906
67 + 101839 = 101906
73 + 101833 = 101906
109 + 101797 = 101906
157 + 101749 = 101906
307 + 101599 = 101906
373 + 101533 = 101906

Showing the first eight; more decompositions exist.
