Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460676, here are decompositions:

19 + 31460657 = 31460676
29 + 31460647 = 31460676
67 + 31460609 = 31460676
127 + 31460549 = 31460676
139 + 31460537 = 31460676
167 + 31460509 = 31460676
179 + 31460497 = 31460676
193 + 31460483 = 31460676

Showing the first eight; more decompositions exist.
