Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73186, here are decompositions:

5 + 73181 = 73186
53 + 73133 = 73186
59 + 73127 = 73186
107 + 73079 = 73186
149 + 73037 = 73186
167 + 73019 = 73186
173 + 73013 = 73186
227 + 72959 = 73186

Showing the first eight; more decompositions exist.
