Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71636, here are decompositions:

3 + 71633 = 71636
43 + 71593 = 71636
67 + 71569 = 71636
73 + 71563 = 71636
109 + 71527 = 71636
157 + 71479 = 71636
163 + 71473 = 71636
193 + 71443 = 71636

Showing the first eight; more decompositions exist.
