Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534692, here are decompositions:

23 + 31534669 = 31534692
41 + 31534651 = 31534692
61 + 31534631 = 31534692
103 + 31534589 = 31534692
131 + 31534561 = 31534692
139 + 31534553 = 31534692
149 + 31534543 = 31534692
191 + 31534501 = 31534692

Showing the first eight; more decompositions exist.
