Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11490, here are decompositions:

7 + 11483 = 11490
19 + 11471 = 11490
23 + 11467 = 11490
43 + 11447 = 11490
47 + 11443 = 11490
53 + 11437 = 11490
67 + 11423 = 11490
79 + 11411 = 11490

Showing the first eight; more decompositions exist.
