Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470004, here are decompositions:

17 + 31469987 = 31470004
101 + 31469903 = 31470004
191 + 31469813 = 31470004
263 + 31469741 = 31470004
281 + 31469723 = 31470004
383 + 31469621 = 31470004
443 + 31469561 = 31470004
491 + 31469513 = 31470004

Showing the first eight; more decompositions exist.
