Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2490, here are decompositions:

13 + 2477 = 2490
17 + 2473 = 2490
23 + 2467 = 2490
31 + 2459 = 2490
43 + 2447 = 2490
53 + 2437 = 2490
67 + 2423 = 2490
73 + 2417 = 2490

Showing the first eight; more decompositions exist.
