Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150618, here are decompositions:

7 + 150611 = 150618
11 + 150607 = 150618
29 + 150589 = 150618
31 + 150587 = 150618
47 + 150571 = 150618
59 + 150559 = 150618
67 + 150551 = 150618
101 + 150517 = 150618

Showing the first eight; more decompositions exist.
