Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587182, here are decompositions:

31 + 31587151 = 31587182
163 + 31587019 = 31587182
241 + 31586941 = 31587182
313 + 31586869 = 31587182
373 + 31586809 = 31587182
379 + 31586803 = 31587182
439 + 31586743 = 31587182
463 + 31586719 = 31587182

Showing the first eight; more decompositions exist.
