Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479706, here are decompositions:

59 + 31479647 = 31479706
113 + 31479593 = 31479706
149 + 31479557 = 31479706
239 + 31479467 = 31479706
509 + 31479197 = 31479706
773 + 31478933 = 31479706
1223 + 31478483 = 31479706
1277 + 31478429 = 31479706

Showing the first eight; more decompositions exist.
