Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523434, here are decompositions:

23 + 31523411 = 31523434
53 + 31523381 = 31523434
167 + 31523267 = 31523434
191 + 31523243 = 31523434
197 + 31523237 = 31523434
227 + 31523207 = 31523434
233 + 31523201 = 31523434
353 + 31523081 = 31523434

Showing the first eight; more decompositions exist.
