Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533544, here are decompositions:

11 + 31533533 = 31533544
47 + 31533497 = 31533544
83 + 31533461 = 31533544
113 + 31533431 = 31533544
131 + 31533413 = 31533544
173 + 31533371 = 31533544
353 + 31533191 = 31533544
401 + 31533143 = 31533544

Showing the first eight; more decompositions exist.
