Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464382, here are decompositions:

23 + 31464359 = 31464382
41 + 31464341 = 31464382
101 + 31464281 = 31464382
113 + 31464269 = 31464382
149 + 31464233 = 31464382
233 + 31464149 = 31464382
239 + 31464143 = 31464382
419 + 31463963 = 31464382

Showing the first eight; more decompositions exist.
