Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479452, here are decompositions:

13 + 31479439 = 31479452
31 + 31479421 = 31479452
163 + 31479289 = 31479452
181 + 31479271 = 31479452
211 + 31479241 = 31479452
379 + 31479073 = 31479452
421 + 31479031 = 31479452
541 + 31478911 = 31479452

Showing the first eight; more decompositions exist.
