Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470192, here are decompositions:

41 + 31470151 = 31470192
179 + 31470013 = 31470192
239 + 31469953 = 31470192
269 + 31469923 = 31470192
331 + 31469861 = 31470192
379 + 31469813 = 31470192
409 + 31469783 = 31470192
431 + 31469761 = 31470192

Showing the first eight; more decompositions exist.
