Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72190, here are decompositions:

17 + 72173 = 72190
23 + 72167 = 72190
29 + 72161 = 72190
89 + 72101 = 72190
101 + 72089 = 72190
113 + 72077 = 72190
137 + 72053 = 72190
191 + 71999 = 72190

Showing the first eight; more decompositions exist.
