Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470332, here are decompositions:

73 + 31470259 = 31470332
109 + 31470223 = 31470332
139 + 31470193 = 31470332
181 + 31470151 = 31470332
379 + 31469953 = 31470332
409 + 31469923 = 31470332
571 + 31469761 = 31470332
601 + 31469731 = 31470332

Showing the first eight; more decompositions exist.
