Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502452, here are decompositions:

11 + 31502441 = 31502452
89 + 31502363 = 31502452
173 + 31502279 = 31502452
239 + 31502213 = 31502452
263 + 31502189 = 31502452
269 + 31502183 = 31502452
353 + 31502099 = 31502452
701 + 31501751 = 31502452

Showing the first eight; more decompositions exist.
