Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534044, here are decompositions:

11 + 31534033 = 31534044
173 + 31533871 = 31534044
197 + 31533847 = 31534044
211 + 31533833 = 31534044
271 + 31533773 = 31534044
281 + 31533763 = 31534044
337 + 31533707 = 31534044
383 + 31533661 = 31534044

Showing the first eight; more decompositions exist.
