Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150642, here are decompositions:

31 + 150611 = 150642
53 + 150589 = 150642
59 + 150583 = 150642
71 + 150571 = 150642
83 + 150559 = 150642
109 + 150533 = 150642
139 + 150503 = 150642
211 + 150431 = 150642

Showing the first eight; more decompositions exist.
