Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40126, here are decompositions:

3 + 40123 = 40126
89 + 40037 = 40126
113 + 40013 = 40126
137 + 39989 = 40126
173 + 39953 = 40126
197 + 39929 = 40126
239 + 39887 = 40126
257 + 39869 = 40126

Showing the first eight; more decompositions exist.
