Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162618, here are decompositions:

7 + 162611 = 162618
17 + 162601 = 162618
41 + 162577 = 162618
61 + 162557 = 162618
89 + 162529 = 162618
101 + 162517 = 162618
167 + 162451 = 162618
179 + 162439 = 162618

Showing the first eight; more decompositions exist.
