Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470014, here are decompositions:

61 + 31469953 = 31470014
157 + 31469857 = 31470014
283 + 31469731 = 31470014
487 + 31469527 = 31470014
547 + 31469467 = 31470014
571 + 31469443 = 31470014
607 + 31469407 = 31470014
661 + 31469353 = 31470014

Showing the first eight; more decompositions exist.
