Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587062, here are decompositions:

43 + 31587019 = 31587062
193 + 31586869 = 31587062
223 + 31586839 = 31587062
271 + 31586791 = 31587062
373 + 31586689 = 31587062
601 + 31586461 = 31587062
751 + 31586311 = 31587062
1009 + 31586053 = 31587062

Showing the first eight; more decompositions exist.
