Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535562, here are decompositions:

11 + 31535551 = 31535562
13 + 31535549 = 31535562
59 + 31535503 = 31535562
139 + 31535423 = 31535562
151 + 31535411 = 31535562
181 + 31535381 = 31535562
241 + 31535321 = 31535562
251 + 31535311 = 31535562

Showing the first eight; more decompositions exist.
