Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150540, here are decompositions:

7 + 150533 = 150540
17 + 150523 = 150540
23 + 150517 = 150540
37 + 150503 = 150540
43 + 150497 = 150540
67 + 150473 = 150540
101 + 150439 = 150540
109 + 150431 = 150540

Showing the first eight; more decompositions exist.
