Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502362, here are decompositions:

29 + 31502333 = 31502362
83 + 31502279 = 31502362
149 + 31502213 = 31502362
173 + 31502189 = 31502362
179 + 31502183 = 31502362
233 + 31502129 = 31502362
263 + 31502099 = 31502362
383 + 31501979 = 31502362

Showing the first eight; more decompositions exist.
