Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533776, here are decompositions:

3 + 31533773 = 31533776
7 + 31533769 = 31533776
13 + 31533763 = 31533776
139 + 31533637 = 31533776
163 + 31533613 = 31533776
229 + 31533547 = 31533776
277 + 31533499 = 31533776
367 + 31533409 = 31533776

Showing the first eight; more decompositions exist.
