Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31936, here are decompositions:

29 + 31907 = 31936
53 + 31883 = 31936
89 + 31847 = 31936
137 + 31799 = 31936
167 + 31769 = 31936
269 + 31667 = 31936
293 + 31643 = 31936
353 + 31583 = 31936

Showing the first eight; more decompositions exist.
