Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86490, here are decompositions:

13 + 86477 = 86490
23 + 86467 = 86490
29 + 86461 = 86490
37 + 86453 = 86490
67 + 86423 = 86490
101 + 86389 = 86490
109 + 86381 = 86490
137 + 86353 = 86490

Showing the first eight; more decompositions exist.
