Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159618, here are decompositions:

29 + 159589 = 159618
47 + 159571 = 159618
79 + 159539 = 159618
97 + 159521 = 159618
127 + 159491 = 159618
149 + 159469 = 159618
181 + 159437 = 159618
197 + 159421 = 159618

Showing the first eight; more decompositions exist.
