Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72186, here are decompositions:

13 + 72173 = 72186
17 + 72169 = 72186
19 + 72167 = 72186
47 + 72139 = 72186
83 + 72103 = 72186
97 + 72089 = 72186
109 + 72077 = 72186
113 + 72073 = 72186

Showing the first eight; more decompositions exist.
