Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461460, here are decompositions:

3 + 31461457 = 31461460
47 + 31461413 = 31461460
167 + 31461293 = 31461460
179 + 31461281 = 31461460
269 + 31461191 = 31461460
281 + 31461179 = 31461460
311 + 31461149 = 31461460
347 + 31461113 = 31461460

Showing the first eight; more decompositions exist.
