Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470066, here are decompositions:

29 + 31470037 = 31470066
53 + 31470013 = 31470066
79 + 31469987 = 31470066
113 + 31469953 = 31470066
163 + 31469903 = 31470066
269 + 31469797 = 31470066
283 + 31469783 = 31470066
443 + 31469623 = 31470066

Showing the first eight; more decompositions exist.
