Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463296, here are decompositions:

47 + 31463249 = 31463296
83 + 31463213 = 31463296
149 + 31463147 = 31463296
173 + 31463123 = 31463296
197 + 31463099 = 31463296
233 + 31463063 = 31463296
317 + 31462979 = 31463296
419 + 31462877 = 31463296

Showing the first eight; more decompositions exist.
