Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543726, here are decompositions:

3 + 31543723 = 31543726
29 + 31543697 = 31543726
83 + 31543643 = 31543726
197 + 31543529 = 31543726
503 + 31543223 = 31543726
509 + 31543217 = 31543726
563 + 31543163 = 31543726
593 + 31543133 = 31543726

Showing the first eight; more decompositions exist.
