Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464412, here are decompositions:

3 + 31464409 = 31464412
11 + 31464401 = 31464412
53 + 31464359 = 31464412
71 + 31464341 = 31464412
131 + 31464281 = 31464412
179 + 31464233 = 31464412
263 + 31464149 = 31464412
269 + 31464143 = 31464412

Showing the first eight; more decompositions exist.
