Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151494, here are decompositions:

11 + 151483 = 151494
17 + 151477 = 151494
23 + 151471 = 151494
43 + 151451 = 151494
61 + 151433 = 151494
71 + 151423 = 151494
97 + 151397 = 151494
103 + 151391 = 151494

Showing the first eight; more decompositions exist.
