Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464286, here are decompositions:

5 + 31464281 = 31464286
17 + 31464269 = 31464286
53 + 31464233 = 31464286
137 + 31464149 = 31464286
149 + 31464137 = 31464286
239 + 31464047 = 31464286
389 + 31463897 = 31464286
443 + 31463843 = 31464286

Showing the first eight; more decompositions exist.
