Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535452, here are decompositions:

23 + 31535429 = 31535452
29 + 31535423 = 31535452
41 + 31535411 = 31535452
71 + 31535381 = 31535452
131 + 31535321 = 31535452
233 + 31535219 = 31535452
239 + 31535213 = 31535452
269 + 31535183 = 31535452

Showing the first eight; more decompositions exist.
