Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535416, here are decompositions:

5 + 31535411 = 31535416
89 + 31535327 = 31535416
197 + 31535219 = 31535416
233 + 31535183 = 31535416
293 + 31535123 = 31535416
359 + 31535057 = 31535416
383 + 31535033 = 31535416
503 + 31534913 = 31535416

Showing the first eight; more decompositions exist.
