Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479884, here are decompositions:

3 + 31479881 = 31479884
67 + 31479817 = 31479884
127 + 31479757 = 31479884
307 + 31479577 = 31479884
367 + 31479517 = 31479884
463 + 31479421 = 31479884
547 + 31479337 = 31479884
577 + 31479307 = 31479884

Showing the first eight; more decompositions exist.
