Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534382, here are decompositions:

13 + 31534369 = 31534382
151 + 31534231 = 31534382
199 + 31534183 = 31534382
241 + 31534141 = 31534382
331 + 31534051 = 31534382
349 + 31534033 = 31534382
433 + 31533949 = 31534382
463 + 31533919 = 31534382

Showing the first eight; more decompositions exist.
