Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535434, here are decompositions:

5 + 31535429 = 31535434
11 + 31535423 = 31535434
17 + 31535417 = 31535434
23 + 31535411 = 31535434
53 + 31535381 = 31535434
107 + 31535327 = 31535434
113 + 31535321 = 31535434
251 + 31535183 = 31535434

Showing the first eight; more decompositions exist.
