Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587034, here are decompositions:

5 + 31587029 = 31587034
107 + 31586927 = 31587034
113 + 31586921 = 31587034
131 + 31586903 = 31587034
317 + 31586717 = 31587034
443 + 31586591 = 31587034
491 + 31586543 = 31587034
587 + 31586447 = 31587034

Showing the first eight; more decompositions exist.
