Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500276, here are decompositions:

13 + 31500263 = 31500276
79 + 31500197 = 31500276
83 + 31500193 = 31500276
89 + 31500187 = 31500276
127 + 31500149 = 31500276
163 + 31500113 = 31500276
193 + 31500083 = 31500276
229 + 31500047 = 31500276

Showing the first eight; more decompositions exist.
