Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162828, here are decompositions:

5 + 162823 = 162828
7 + 162821 = 162828
37 + 162791 = 162828
41 + 162787 = 162828
79 + 162749 = 162828
89 + 162739 = 162828
97 + 162731 = 162828
101 + 162727 = 162828

Showing the first eight; more decompositions exist.
