Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171618, here are decompositions:

47 + 171571 = 171618
59 + 171559 = 171618
79 + 171539 = 171618
89 + 171529 = 171618
101 + 171517 = 171618
127 + 171491 = 171618
137 + 171481 = 171618
149 + 171469 = 171618

Showing the first eight; more decompositions exist.
