Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464658, here are decompositions:

41 + 31464617 = 31464658
101 + 31464557 = 31464658
149 + 31464509 = 31464658
257 + 31464401 = 31464658
317 + 31464341 = 31464658
389 + 31464269 = 31464658
509 + 31464149 = 31464658
521 + 31464137 = 31464658

Showing the first eight; more decompositions exist.
