Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552882, here are decompositions:

3 + 31552879 = 31552882
29 + 31552853 = 31552882
149 + 31552733 = 31552882
173 + 31552709 = 31552882
239 + 31552643 = 31552882
293 + 31552589 = 31552882
461 + 31552421 = 31552882
479 + 31552403 = 31552882

Showing the first eight; more decompositions exist.
