Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502476, here are decompositions:

17 + 31502459 = 31502476
113 + 31502363 = 31502476
197 + 31502279 = 31502476
233 + 31502243 = 31502476
263 + 31502213 = 31502476
293 + 31502183 = 31502476
347 + 31502129 = 31502476
563 + 31501913 = 31502476

Showing the first eight; more decompositions exist.
