Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40488, here are decompositions:

5 + 40483 = 40488
17 + 40471 = 40488
29 + 40459 = 40488
59 + 40429 = 40488
61 + 40427 = 40488
101 + 40387 = 40488
127 + 40361 = 40488
131 + 40357 = 40488

Showing the first eight; more decompositions exist.
