Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470002, here are decompositions:

13 + 31469989 = 31470002
79 + 31469923 = 31470002
241 + 31469761 = 31470002
271 + 31469731 = 31470002
313 + 31469689 = 31470002
331 + 31469671 = 31470002
349 + 31469653 = 31470002
373 + 31469629 = 31470002

Showing the first eight; more decompositions exist.
