Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587734, here are decompositions:

37 + 31587697 = 31587734
307 + 31587427 = 31587734
313 + 31587421 = 31587734
337 + 31587397 = 31587734
463 + 31587271 = 31587734
643 + 31587091 = 31587734
991 + 31586743 = 31587734
1063 + 31586671 = 31587734

Showing the first eight; more decompositions exist.
