Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502494, here are decompositions:

5 + 31502489 = 31502494
11 + 31502483 = 31502494
53 + 31502441 = 31502494
131 + 31502363 = 31502494
251 + 31502243 = 31502494
281 + 31502213 = 31502494
311 + 31502183 = 31502494
347 + 31502147 = 31502494

Showing the first eight; more decompositions exist.
