Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41490, here are decompositions:

11 + 41479 = 41490
23 + 41467 = 41490
37 + 41453 = 41490
47 + 41443 = 41490
79 + 41411 = 41490
101 + 41389 = 41490
103 + 41387 = 41490
109 + 41381 = 41490

Showing the first eight; more decompositions exist.
