Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150638, here are decompositions:

31 + 150607 = 150638
67 + 150571 = 150638
79 + 150559 = 150638
199 + 150439 = 150638
211 + 150427 = 150638
337 + 150301 = 150638
421 + 150217 = 150638
487 + 150151 = 150638

Showing the first eight; more decompositions exist.
