Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464616, here are decompositions:

59 + 31464557 = 31464616
107 + 31464509 = 31464616
173 + 31464443 = 31464616
257 + 31464359 = 31464616
347 + 31464269 = 31464616
383 + 31464233 = 31464616
467 + 31464149 = 31464616
479 + 31464137 = 31464616

Showing the first eight; more decompositions exist.
