Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535464, here are decompositions:

41 + 31535423 = 31535464
47 + 31535417 = 31535464
53 + 31535411 = 31535464
83 + 31535381 = 31535464
137 + 31535327 = 31535464
251 + 31535213 = 31535464
281 + 31535183 = 31535464
293 + 31535171 = 31535464

Showing the first eight; more decompositions exist.
