Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171630, here are decompositions:

13 + 171617 = 171630
47 + 171583 = 171630
59 + 171571 = 171630
71 + 171559 = 171630
89 + 171541 = 171630
101 + 171529 = 171630
113 + 171517 = 171630
139 + 171491 = 171630

Showing the first eight; more decompositions exist.
