Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535412, here are decompositions:

31 + 31535381 = 31535412
71 + 31535341 = 31535412
101 + 31535311 = 31535412
149 + 31535263 = 31535412
179 + 31535233 = 31535412
193 + 31535219 = 31535412
199 + 31535213 = 31535412
229 + 31535183 = 31535412

Showing the first eight; more decompositions exist.
