Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71620, here are decompositions:

23 + 71597 = 71620
71 + 71549 = 71620
83 + 71537 = 71620
137 + 71483 = 71620
149 + 71471 = 71620
167 + 71453 = 71620
191 + 71429 = 71620
233 + 71387 = 71620

Showing the first eight; more decompositions exist.
