Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502248, here are decompositions:

5 + 31502243 = 31502248
59 + 31502189 = 31502248
101 + 31502147 = 31502248
149 + 31502099 = 31502248
269 + 31501979 = 31502248
311 + 31501937 = 31502248
467 + 31501781 = 31502248
521 + 31501727 = 31502248

Showing the first eight; more decompositions exist.
