Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502446, here are decompositions:

5 + 31502441 = 31502446
83 + 31502363 = 31502446
113 + 31502333 = 31502446
167 + 31502279 = 31502446
233 + 31502213 = 31502446
257 + 31502189 = 31502446
263 + 31502183 = 31502446
317 + 31502129 = 31502446

Showing the first eight; more decompositions exist.
