Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152988, here are decompositions:

7 + 152981 = 152988
29 + 152959 = 152988
41 + 152947 = 152988
47 + 152941 = 152988
79 + 152909 = 152988
89 + 152899 = 152988
109 + 152879 = 152988
131 + 152857 = 152988

Showing the first eight; more decompositions exist.
