Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533058, here are decompositions:

59 + 31532999 = 31533058
191 + 31532867 = 31533058
281 + 31532777 = 31533058
419 + 31532639 = 31533058
461 + 31532597 = 31533058
569 + 31532489 = 31533058
719 + 31532339 = 31533058
797 + 31532261 = 31533058

Showing the first eight; more decompositions exist.
