Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470026, here are decompositions:

13 + 31470013 = 31470026
37 + 31469989 = 31470026
73 + 31469953 = 31470026
103 + 31469923 = 31470026
229 + 31469797 = 31470026
337 + 31469689 = 31470026
373 + 31469653 = 31470026
397 + 31469629 = 31470026

Showing the first eight; more decompositions exist.
