Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587176, here are decompositions:

157 + 31587019 = 31587176
307 + 31586869 = 31587176
337 + 31586839 = 31587176
367 + 31586809 = 31587176
373 + 31586803 = 31587176
433 + 31586743 = 31587176
457 + 31586719 = 31587176
487 + 31586689 = 31587176

Showing the first eight; more decompositions exist.
