Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533754, here are decompositions:

47 + 31533707 = 31533754
113 + 31533641 = 31533754
167 + 31533587 = 31533754
173 + 31533581 = 31533754
191 + 31533563 = 31533754
257 + 31533497 = 31533754
293 + 31533461 = 31533754
383 + 31533371 = 31533754

Showing the first eight; more decompositions exist.
