Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479704, here are decompositions:

7 + 31479697 = 31479704
127 + 31479577 = 31479704
163 + 31479541 = 31479704
283 + 31479421 = 31479704
367 + 31479337 = 31479704
397 + 31479307 = 31479704
433 + 31479271 = 31479704
463 + 31479241 = 31479704

Showing the first eight; more decompositions exist.
