Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502464, here are decompositions:

5 + 31502459 = 31502464
23 + 31502441 = 31502464
101 + 31502363 = 31502464
131 + 31502333 = 31502464
251 + 31502213 = 31502464
281 + 31502183 = 31502464
317 + 31502147 = 31502464
557 + 31501907 = 31502464

Showing the first eight; more decompositions exist.
