Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458264, here are decompositions:

67 + 31458197 = 31458264
73 + 31458191 = 31458264
151 + 31458113 = 31458264
181 + 31458083 = 31458264
251 + 31458013 = 31458264
353 + 31457911 = 31458264
421 + 31457843 = 31458264
433 + 31457831 = 31458264

Showing the first eight; more decompositions exist.
