Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101490, here are decompositions:

7 + 101483 = 101490
13 + 101477 = 101490
23 + 101467 = 101490
41 + 101449 = 101490
61 + 101429 = 101490
71 + 101419 = 101490
79 + 101411 = 101490
107 + 101383 = 101490

Showing the first eight; more decompositions exist.
