Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533088, here are decompositions:

89 + 31532999 = 31533088
107 + 31532981 = 31533088
149 + 31532939 = 31533088
311 + 31532777 = 31533088
401 + 31532687 = 31533088
449 + 31532639 = 31533088
491 + 31532597 = 31533088
599 + 31532489 = 31533088

Showing the first eight; more decompositions exist.
