Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40416, here are decompositions:

29 + 40387 = 40416
59 + 40357 = 40416
73 + 40343 = 40416
127 + 40289 = 40416
139 + 40277 = 40416
163 + 40253 = 40416
179 + 40237 = 40416
223 + 40193 = 40416

Showing the first eight; more decompositions exist.
