Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149388, here are decompositions:

7 + 149381 = 149388
11 + 149377 = 149388
17 + 149371 = 149388
37 + 149351 = 149388
47 + 149341 = 149388
79 + 149309 = 149388
101 + 149287 = 149388
131 + 149257 = 149388

Showing the first eight; more decompositions exist.
