Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479512, here are decompositions:

13 + 31479499 = 31479512
73 + 31479439 = 31479512
223 + 31479289 = 31479512
241 + 31479271 = 31479512
271 + 31479241 = 31479512
439 + 31479073 = 31479512
601 + 31478911 = 31479512
661 + 31478851 = 31479512

Showing the first eight; more decompositions exist.
