Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535494, here are decompositions:

71 + 31535423 = 31535494
83 + 31535411 = 31535494
113 + 31535381 = 31535494
167 + 31535327 = 31535494
173 + 31535321 = 31535494
281 + 31535213 = 31535494
311 + 31535183 = 31535494
461 + 31535033 = 31535494

Showing the first eight; more decompositions exist.
