Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40906, here are decompositions:

3 + 40903 = 40906
23 + 40883 = 40906
53 + 40853 = 40906
59 + 40847 = 40906
83 + 40823 = 40906
167 + 40739 = 40906
197 + 40709 = 40906
269 + 40637 = 40906

Showing the first eight; more decompositions exist.
