Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478704, here are decompositions:

3 + 31478701 = 31478704
137 + 31478567 = 31478704
233 + 31478471 = 31478704
293 + 31478411 = 31478704
311 + 31478393 = 31478704
353 + 31478351 = 31478704
557 + 31478147 = 31478704
797 + 31477907 = 31478704

Showing the first eight; more decompositions exist.
