Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523936, here are decompositions:

19 + 31523917 = 31523936
97 + 31523839 = 31523936
229 + 31523707 = 31523936
277 + 31523659 = 31523936
337 + 31523599 = 31523936
397 + 31523539 = 31523936
463 + 31523473 = 31523936
607 + 31523329 = 31523936

Showing the first eight; more decompositions exist.
