Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464208, here are decompositions:

59 + 31464149 = 31464208
71 + 31464137 = 31464208
311 + 31463897 = 31464208
317 + 31463891 = 31464208
359 + 31463849 = 31464208
401 + 31463807 = 31464208
449 + 31463759 = 31464208
491 + 31463717 = 31464208

Showing the first eight; more decompositions exist.
