Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534734, here are decompositions:

5 + 31534729 = 31534734
43 + 31534691 = 31534734
83 + 31534651 = 31534734
97 + 31534637 = 31534734
103 + 31534631 = 31534734
137 + 31534597 = 31534734
173 + 31534561 = 31534734
181 + 31534553 = 31534734

Showing the first eight; more decompositions exist.
