Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587076, here are decompositions:

23 + 31587053 = 31587076
47 + 31587029 = 31587076
137 + 31586939 = 31587076
149 + 31586927 = 31587076
173 + 31586903 = 31587076
197 + 31586879 = 31587076
263 + 31586813 = 31587076
359 + 31586717 = 31587076

Showing the first eight; more decompositions exist.
