Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470060, here are decompositions:

23 + 31470037 = 31470060
47 + 31470013 = 31470060
71 + 31469989 = 31470060
73 + 31469987 = 31470060
107 + 31469953 = 31470060
137 + 31469923 = 31470060
157 + 31469903 = 31470060
199 + 31469861 = 31470060

Showing the first eight; more decompositions exist.
