Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534454, here are decompositions:

13 + 31534441 = 31534454
31 + 31534423 = 31534454
43 + 31534411 = 31534454
157 + 31534297 = 31534454
223 + 31534231 = 31534454
271 + 31534183 = 31534454
313 + 31534141 = 31534454
337 + 31534117 = 31534454

Showing the first eight; more decompositions exist.
