Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535686, here are decompositions:

5 + 31535681 = 31535686
29 + 31535657 = 31535686
47 + 31535639 = 31535686
53 + 31535633 = 31535686
137 + 31535549 = 31535686
257 + 31535429 = 31535686
263 + 31535423 = 31535686
269 + 31535417 = 31535686

Showing the first eight; more decompositions exist.
