Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464718, here are decompositions:

17 + 31464701 = 31464718
101 + 31464617 = 31464718
137 + 31464581 = 31464718
317 + 31464401 = 31464718
359 + 31464359 = 31464718
449 + 31464269 = 31464718
569 + 31464149 = 31464718
797 + 31463921 = 31464718

Showing the first eight; more decompositions exist.
