Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151490, here are decompositions:

7 + 151483 = 151490
13 + 151477 = 151490
19 + 151471 = 151490
61 + 151429 = 151490
67 + 151423 = 151490
109 + 151381 = 151490
151 + 151339 = 151490
211 + 151279 = 151490

Showing the first eight; more decompositions exist.
