Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461348, here are decompositions:

5 + 31461343 = 31461348
7 + 31461341 = 31461348
47 + 31461301 = 31461348
67 + 31461281 = 31461348
157 + 31461191 = 31461348
167 + 31461181 = 31461348
199 + 31461149 = 31461348
311 + 31461037 = 31461348

Showing the first eight; more decompositions exist.
