Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479106, here are decompositions:

5 + 31479101 = 31479106
23 + 31479083 = 31479106
89 + 31479017 = 31479106
137 + 31478969 = 31479106
149 + 31478957 = 31479106
173 + 31478933 = 31479106
467 + 31478639 = 31479106
677 + 31478429 = 31479106

Showing the first eight; more decompositions exist.
