Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152972, here are decompositions:

13 + 152959 = 152972
19 + 152953 = 152972
31 + 152941 = 152972
73 + 152899 = 152972
139 + 152833 = 152972
151 + 152821 = 152972
163 + 152809 = 152972
181 + 152791 = 152972

Showing the first eight; more decompositions exist.
