Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167172, here are decompositions:

13 + 167159 = 167172
23 + 167149 = 167172
53 + 167119 = 167172
59 + 167113 = 167172
73 + 167099 = 167172
101 + 167071 = 167172
139 + 167033 = 167172
149 + 167023 = 167172

Showing the first eight; more decompositions exist.
