Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587114, here are decompositions:

7 + 31587107 = 31587114
23 + 31587091 = 31587114
61 + 31587053 = 31587114
173 + 31586941 = 31587114
193 + 31586921 = 31587114
211 + 31586903 = 31587114
311 + 31586803 = 31587114
397 + 31586717 = 31587114

Showing the first eight; more decompositions exist.
