Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71646, here are decompositions:

13 + 71633 = 71646
53 + 71593 = 71646
83 + 71563 = 71646
97 + 71549 = 71646
109 + 71537 = 71646
163 + 71483 = 71646
167 + 71479 = 71646
173 + 71473 = 71646

Showing the first eight; more decompositions exist.
