Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464388, here are decompositions:

29 + 31464359 = 31464388
47 + 31464341 = 31464388
107 + 31464281 = 31464388
239 + 31464149 = 31464388
251 + 31464137 = 31464388
467 + 31463921 = 31464388
479 + 31463909 = 31464388
491 + 31463897 = 31464388

Showing the first eight; more decompositions exist.
