Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41440, here are decompositions:

29 + 41411 = 41440
41 + 41399 = 41440
53 + 41387 = 41440
59 + 41381 = 41440
83 + 41357 = 41440
89 + 41351 = 41440
107 + 41333 = 41440
197 + 41243 = 41440

Showing the first eight; more decompositions exist.
