Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533488, here are decompositions:

37 + 31533451 = 31533488
79 + 31533409 = 31533488
109 + 31533379 = 31533488
229 + 31533259 = 31533488
397 + 31533091 = 31533488
487 + 31533001 = 31533488
607 + 31532881 = 31533488
739 + 31532749 = 31533488

Showing the first eight; more decompositions exist.
