Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587046, here are decompositions:

17 + 31587029 = 31587046
107 + 31586939 = 31587046
167 + 31586879 = 31587046
233 + 31586813 = 31587046
347 + 31586699 = 31587046
419 + 31586627 = 31587046
467 + 31586579 = 31587046
503 + 31586543 = 31587046

Showing the first eight; more decompositions exist.
