Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162830, here are decompositions:

7 + 162823 = 162830
43 + 162787 = 162830
79 + 162751 = 162830
103 + 162727 = 162830
127 + 162703 = 162830
139 + 162691 = 162830
181 + 162649 = 162830
229 + 162601 = 162830

Showing the first eight; more decompositions exist.
