Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571734, here are decompositions:

3 + 31571731 = 31571734
83 + 31571651 = 31571734
107 + 31571627 = 31571734
113 + 31571621 = 31571734
281 + 31571453 = 31571734
353 + 31571381 = 31571734
401 + 31571333 = 31571734
431 + 31571303 = 31571734

Showing the first eight; more decompositions exist.
