Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534412, here are decompositions:

43 + 31534369 = 31534412
79 + 31534333 = 31534412
181 + 31534231 = 31534412
229 + 31534183 = 31534412
271 + 31534141 = 31534412
379 + 31534033 = 31534412
433 + 31533979 = 31534412
463 + 31533949 = 31534412

Showing the first eight; more decompositions exist.
