Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40814, here are decompositions:

13 + 40801 = 40814
43 + 40771 = 40814
223 + 40591 = 40814
271 + 40543 = 40814
283 + 40531 = 40814
307 + 40507 = 40814
331 + 40483 = 40814
457 + 40357 = 40814

Showing the first eight; more decompositions exist.
