Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535836, here are decompositions:

5 + 31535831 = 31535836
83 + 31535753 = 31535836
89 + 31535747 = 31535836
179 + 31535657 = 31535836
197 + 31535639 = 31535836
419 + 31535417 = 31535836
509 + 31535327 = 31535836
617 + 31535219 = 31535836

Showing the first eight; more decompositions exist.
