Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603882, here are decompositions:

3 + 31603879 = 31603882
5 + 31603877 = 31603882
53 + 31603829 = 31603882
131 + 31603751 = 31603882
173 + 31603709 = 31603882
239 + 31603643 = 31603882
269 + 31603613 = 31603882
521 + 31603361 = 31603882

Showing the first eight; more decompositions exist.
