Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502236, here are decompositions:

23 + 31502213 = 31502236
47 + 31502189 = 31502236
53 + 31502183 = 31502236
89 + 31502147 = 31502236
107 + 31502129 = 31502236
137 + 31502099 = 31502236
257 + 31501979 = 31502236
509 + 31501727 = 31502236

Showing the first eight; more decompositions exist.
