Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554832, here are decompositions:

3 + 31554829 = 31554832
41 + 31554791 = 31554832
83 + 31554749 = 31554832
173 + 31554659 = 31554832
191 + 31554641 = 31554832
263 + 31554569 = 31554832
293 + 31554539 = 31554832
359 + 31554473 = 31554832

Showing the first eight; more decompositions exist.
