Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40100, here are decompositions:

7 + 40093 = 40100
13 + 40087 = 40100
37 + 40063 = 40100
61 + 40039 = 40100
163 + 39937 = 40100
199 + 39901 = 40100
223 + 39877 = 40100
271 + 39829 = 40100

Showing the first eight; more decompositions exist.
