Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587094, here are decompositions:

3 + 31587091 = 31587094
41 + 31587053 = 31587094
167 + 31586927 = 31587094
173 + 31586921 = 31587094
191 + 31586903 = 31587094
281 + 31586813 = 31587094
467 + 31586627 = 31587094
503 + 31586591 = 31587094

Showing the first eight; more decompositions exist.
