Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479606, here are decompositions:

13 + 31479593 = 31479606
17 + 31479589 = 31479606
29 + 31479577 = 31479606
47 + 31479559 = 31479606
89 + 31479517 = 31479606
107 + 31479499 = 31479606
139 + 31479467 = 31479606
149 + 31479457 = 31479606

Showing the first eight; more decompositions exist.
