Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533898, here are decompositions:

59 + 31533839 = 31533898
107 + 31533791 = 31533898
191 + 31533707 = 31533898
239 + 31533659 = 31533898
257 + 31533641 = 31533898
311 + 31533587 = 31533898
317 + 31533581 = 31533898
401 + 31533497 = 31533898

Showing the first eight; more decompositions exist.
