Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535330, here are decompositions:

3 + 31535327 = 31535330
19 + 31535311 = 31535330
67 + 31535263 = 31535330
97 + 31535233 = 31535330
103 + 31535227 = 31535330
157 + 31535173 = 31535330
199 + 31535131 = 31535330
223 + 31535107 = 31535330

Showing the first eight; more decompositions exist.
