Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534654, here are decompositions:

3 + 31534651 = 31534654
17 + 31534637 = 31534654
23 + 31534631 = 31534654
101 + 31534553 = 31534654
167 + 31534487 = 31534654
197 + 31534457 = 31534654
227 + 31534427 = 31534654
311 + 31534343 = 31534654

Showing the first eight; more decompositions exist.
