Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497276, here are decompositions:

47 + 31497229 = 31497276
53 + 31497223 = 31497276
89 + 31497187 = 31497276
137 + 31497139 = 31497276
149 + 31497127 = 31497276
193 + 31497083 = 31497276
269 + 31497007 = 31497276
313 + 31496963 = 31497276

Showing the first eight; more decompositions exist.
