Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151140, here are decompositions:

19 + 151121 = 151140
83 + 151057 = 151140
89 + 151051 = 151140
113 + 151027 = 151140
127 + 151013 = 151140
131 + 151009 = 151140
149 + 150991 = 151140
151 + 150989 = 151140

Showing the first eight; more decompositions exist.
