Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502244, here are decompositions:

31 + 31502213 = 31502244
61 + 31502183 = 31502244
83 + 31502161 = 31502244
97 + 31502147 = 31502244
113 + 31502131 = 31502244
131 + 31502113 = 31502244
307 + 31501937 = 31502244
331 + 31501913 = 31502244

Showing the first eight; more decompositions exist.
