Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590276, here are decompositions:

7 + 31590269 = 31590276
13 + 31590263 = 31590276
89 + 31590187 = 31590276
127 + 31590149 = 31590276
139 + 31590137 = 31590276
239 + 31590037 = 31590276
269 + 31590007 = 31590276
293 + 31589983 = 31590276

Showing the first eight; more decompositions exist.
