Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150990, here are decompositions:

11 + 150979 = 150990
23 + 150967 = 150990
29 + 150961 = 150990
31 + 150959 = 150990
61 + 150929 = 150990
71 + 150919 = 150990
83 + 150907 = 150990
89 + 150901 = 150990

Showing the first eight; more decompositions exist.
