Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150978, here are decompositions:

11 + 150967 = 150978
17 + 150961 = 150978
19 + 150959 = 150978
59 + 150919 = 150978
71 + 150907 = 150978
89 + 150889 = 150978
97 + 150881 = 150978
109 + 150869 = 150978

Showing the first eight; more decompositions exist.
