Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172162, here are decompositions:

5 + 172157 = 172162
83 + 172079 = 172162
113 + 172049 = 172162
131 + 172031 = 172162
233 + 171929 = 172162
239 + 171923 = 172162
281 + 171881 = 172162
293 + 171869 = 172162

Showing the first eight; more decompositions exist.
