Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463326, here are decompositions:

5 + 31463321 = 31463326
113 + 31463213 = 31463326
179 + 31463147 = 31463326
227 + 31463099 = 31463326
239 + 31463087 = 31463326
263 + 31463063 = 31463326
347 + 31462979 = 31463326
449 + 31462877 = 31463326

Showing the first eight; more decompositions exist.
