Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39906, here are decompositions:

5 + 39901 = 39906
19 + 39887 = 39906
23 + 39883 = 39906
29 + 39877 = 39906
37 + 39869 = 39906
43 + 39863 = 39906
59 + 39847 = 39906
67 + 39839 = 39906

Showing the first eight; more decompositions exist.
