Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40738, here are decompositions:

29 + 40709 = 40738
41 + 40697 = 40738
101 + 40637 = 40738
179 + 40559 = 40738
239 + 40499 = 40738
251 + 40487 = 40738
311 + 40427 = 40738
449 + 40289 = 40738

Showing the first eight; more decompositions exist.
