Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535514, here are decompositions:

11 + 31535503 = 31535514
47 + 31535467 = 31535514
97 + 31535417 = 31535514
103 + 31535411 = 31535514
137 + 31535377 = 31535514
173 + 31535341 = 31535514
193 + 31535321 = 31535514
251 + 31535263 = 31535514

Showing the first eight; more decompositions exist.
