Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535262, here are decompositions:

29 + 31535233 = 31535262
43 + 31535219 = 31535262
79 + 31535183 = 31535262
89 + 31535173 = 31535262
131 + 31535131 = 31535262
139 + 31535123 = 31535262
149 + 31535113 = 31535262
179 + 31535083 = 31535262

Showing the first eight; more decompositions exist.
