Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460854, here are decompositions:

3 + 31460851 = 31460854
17 + 31460837 = 31460854
23 + 31460831 = 31460854
71 + 31460783 = 31460854
137 + 31460717 = 31460854
197 + 31460657 = 31460854
317 + 31460537 = 31460854
563 + 31460291 = 31460854

Showing the first eight; more decompositions exist.
