Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479248, here are decompositions:

7 + 31479241 = 31479248
337 + 31478911 = 31479248
397 + 31478851 = 31479248
547 + 31478701 = 31479248
601 + 31478647 = 31479248
727 + 31478521 = 31479248
769 + 31478479 = 31479248
859 + 31478389 = 31479248

Showing the first eight; more decompositions exist.
