Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534262, here are decompositions:

31 + 31534231 = 31534262
79 + 31534183 = 31534262
211 + 31534051 = 31534262
229 + 31534033 = 31534262
283 + 31533979 = 31534262
313 + 31533949 = 31534262
433 + 31533829 = 31534262
439 + 31533823 = 31534262

Showing the first eight; more decompositions exist.
