Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453692, here are decompositions:

13 + 31453679 = 31453692
41 + 31453651 = 31453692
163 + 31453529 = 31453692
191 + 31453501 = 31453692
229 + 31453463 = 31453692
271 + 31453421 = 31453692
331 + 31453361 = 31453692
359 + 31453333 = 31453692

Showing the first eight; more decompositions exist.
