Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535370, here are decompositions:

29 + 31535341 = 31535370
43 + 31535327 = 31535370
59 + 31535311 = 31535370
107 + 31535263 = 31535370
137 + 31535233 = 31535370
151 + 31535219 = 31535370
157 + 31535213 = 31535370
197 + 31535173 = 31535370

Showing the first eight; more decompositions exist.
