Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73180, here are decompositions:

47 + 73133 = 73180
53 + 73127 = 73180
59 + 73121 = 73180
89 + 73091 = 73180
101 + 73079 = 73180
137 + 73043 = 73180
167 + 73013 = 73180
227 + 72953 = 73180

Showing the first eight; more decompositions exist.
