Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535470, here are decompositions:

3 + 31535467 = 31535470
41 + 31535429 = 31535470
47 + 31535423 = 31535470
53 + 31535417 = 31535470
59 + 31535411 = 31535470
89 + 31535381 = 31535470
149 + 31535321 = 31535470
251 + 31535219 = 31535470

Showing the first eight; more decompositions exist.
