Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502284, here are decompositions:

5 + 31502279 = 31502284
41 + 31502243 = 31502284
71 + 31502213 = 31502284
101 + 31502183 = 31502284
137 + 31502147 = 31502284
347 + 31501937 = 31502284
461 + 31501823 = 31502284
503 + 31501781 = 31502284

Showing the first eight; more decompositions exist.
