Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72148, here are decompositions:

47 + 72101 = 72148
59 + 72089 = 72148
71 + 72077 = 72148
101 + 72047 = 72148
149 + 71999 = 72148
239 + 71909 = 72148
269 + 71879 = 72148
281 + 71867 = 72148

Showing the first eight; more decompositions exist.
