Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40418, here are decompositions:

31 + 40387 = 40418
61 + 40357 = 40418
67 + 40351 = 40418
181 + 40237 = 40418
229 + 40189 = 40418
241 + 40177 = 40418
307 + 40111 = 40418
331 + 40087 = 40418

Showing the first eight; more decompositions exist.
