Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171612, here are decompositions:

29 + 171583 = 171612
41 + 171571 = 171612
53 + 171559 = 171612
59 + 171553 = 171612
71 + 171541 = 171612
73 + 171539 = 171612
83 + 171529 = 171612
131 + 171481 = 171612

Showing the first eight; more decompositions exist.
