Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464694, here are decompositions:

113 + 31464581 = 31464694
137 + 31464557 = 31464694
251 + 31464443 = 31464694
293 + 31464401 = 31464694
353 + 31464341 = 31464694
461 + 31464233 = 31464694
557 + 31464137 = 31464694
647 + 31464047 = 31464694

Showing the first eight; more decompositions exist.
