Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479726, here are decompositions:

7 + 31479719 = 31479726
29 + 31479697 = 31479726
79 + 31479647 = 31479726
107 + 31479619 = 31479726
137 + 31479589 = 31479726
149 + 31479577 = 31479726
167 + 31479559 = 31479726
227 + 31479499 = 31479726

Showing the first eight; more decompositions exist.
