Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535532, here are decompositions:

29 + 31535503 = 31535532
103 + 31535429 = 31535532
109 + 31535423 = 31535532
113 + 31535419 = 31535532
151 + 31535381 = 31535532
191 + 31535341 = 31535532
211 + 31535321 = 31535532
269 + 31535263 = 31535532

Showing the first eight; more decompositions exist.
