Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479316, here are decompositions:

17 + 31479299 = 31479316
47 + 31479269 = 31479316
233 + 31479083 = 31479316
347 + 31478969 = 31479316
359 + 31478957 = 31479316
383 + 31478933 = 31479316
509 + 31478807 = 31479316
677 + 31478639 = 31479316

Showing the first eight; more decompositions exist.
