Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152980, here are decompositions:

41 + 152939 = 152980
71 + 152909 = 152980
83 + 152897 = 152980
101 + 152879 = 152980
137 + 152843 = 152980
197 + 152783 = 152980
227 + 152753 = 152980
251 + 152729 = 152980

Showing the first eight; more decompositions exist.
