Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40550, here are decompositions:

7 + 40543 = 40550
19 + 40531 = 40550
31 + 40519 = 40550
43 + 40507 = 40550
67 + 40483 = 40550
79 + 40471 = 40550
127 + 40423 = 40550
163 + 40387 = 40550

Showing the first eight; more decompositions exist.
