Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540692, here are decompositions:

13 + 31540679 = 31540692
23 + 31540669 = 31540692
41 + 31540651 = 31540692
61 + 31540631 = 31540692
163 + 31540529 = 31540692
191 + 31540501 = 31540692
193 + 31540499 = 31540692
199 + 31540493 = 31540692

Showing the first eight; more decompositions exist.
