Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479964, here are decompositions:

3 + 31479961 = 31479964
17 + 31479947 = 31479964
83 + 31479881 = 31479964
107 + 31479857 = 31479964
227 + 31479737 = 31479964
293 + 31479671 = 31479964
317 + 31479647 = 31479964
863 + 31479101 = 31479964

Showing the first eight; more decompositions exist.
