Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40436, here are decompositions:

3 + 40433 = 40436
7 + 40429 = 40436
13 + 40423 = 40436
79 + 40357 = 40436
199 + 40237 = 40436
223 + 40213 = 40436
283 + 40153 = 40436
307 + 40129 = 40436

Showing the first eight; more decompositions exist.
