Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535202, here are decompositions:

19 + 31535183 = 31535202
29 + 31535173 = 31535202
31 + 31535171 = 31535202
59 + 31535143 = 31535202
71 + 31535131 = 31535202
79 + 31535123 = 31535202
89 + 31535113 = 31535202
191 + 31535011 = 31535202

Showing the first eight; more decompositions exist.
