Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172148, here are decompositions:

79 + 172069 = 172148
127 + 172021 = 172148
139 + 172009 = 172148
211 + 171937 = 172148
271 + 171877 = 172148
337 + 171811 = 172148
349 + 171799 = 172148
577 + 171571 = 172148

Showing the first eight; more decompositions exist.
