Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464418, here are decompositions:

17 + 31464401 = 31464418
59 + 31464359 = 31464418
137 + 31464281 = 31464418
149 + 31464269 = 31464418
269 + 31464149 = 31464418
281 + 31464137 = 31464418
509 + 31463909 = 31464418
521 + 31463897 = 31464418

Showing the first eight; more decompositions exist.
