Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535526, here are decompositions:

23 + 31535503 = 31535526
59 + 31535467 = 31535526
97 + 31535429 = 31535526
103 + 31535423 = 31535526
107 + 31535419 = 31535526
109 + 31535417 = 31535526
149 + 31535377 = 31535526
199 + 31535327 = 31535526

Showing the first eight; more decompositions exist.
