Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534698, here are decompositions:

7 + 31534691 = 31534698
29 + 31534669 = 31534698
47 + 31534651 = 31534698
61 + 31534637 = 31534698
67 + 31534631 = 31534698
101 + 31534597 = 31534698
109 + 31534589 = 31534698
137 + 31534561 = 31534698

Showing the first eight; more decompositions exist.
