Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153072, here are decompositions:

5 + 153067 = 153072
13 + 153059 = 153072
71 + 153001 = 153072
79 + 152993 = 153072
83 + 152989 = 153072
113 + 152959 = 153072
131 + 152941 = 153072
163 + 152909 = 153072

Showing the first eight; more decompositions exist.
