Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463254, here are decompositions:

5 + 31463249 = 31463254
41 + 31463213 = 31463254
107 + 31463147 = 31463254
131 + 31463123 = 31463254
167 + 31463087 = 31463254
191 + 31463063 = 31463254
353 + 31462901 = 31463254
443 + 31462811 = 31463254

Showing the first eight; more decompositions exist.
