Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171672, here are decompositions:

13 + 171659 = 171672
19 + 171653 = 171672
31 + 171641 = 171672
43 + 171629 = 171672
89 + 171583 = 171672
101 + 171571 = 171672
113 + 171559 = 171672
131 + 171541 = 171672

Showing the first eight; more decompositions exist.
