Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162718, here are decompositions:

5 + 162713 = 162718
41 + 162677 = 162718
47 + 162671 = 162718
89 + 162629 = 162718
107 + 162611 = 162718
191 + 162527 = 162718
359 + 162359 = 162718
431 + 162287 = 162718

Showing the first eight; more decompositions exist.
