Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533958, here are decompositions:

47 + 31533911 = 31533958
167 + 31533791 = 31533958
251 + 31533707 = 31533958
317 + 31533641 = 31533958
347 + 31533611 = 31533958
359 + 31533599 = 31533958
461 + 31533497 = 31533958
509 + 31533449 = 31533958

Showing the first eight; more decompositions exist.
