Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535804, here are decompositions:

7 + 31535797 = 31535804
211 + 31535593 = 31535804
337 + 31535467 = 31535804
463 + 31535341 = 31535804
541 + 31535263 = 31535804
571 + 31535233 = 31535804
577 + 31535227 = 31535804
631 + 31535173 = 31535804

Showing the first eight; more decompositions exist.
