Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535302, here are decompositions:

83 + 31535219 = 31535302
89 + 31535213 = 31535302
131 + 31535171 = 31535302
179 + 31535123 = 31535302
269 + 31535033 = 31535302
389 + 31534913 = 31535302
431 + 31534871 = 31535302
503 + 31534799 = 31535302

Showing the first eight; more decompositions exist.
