Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470070, here are decompositions:

3 + 31470067 = 31470070
83 + 31469987 = 31470070
167 + 31469903 = 31470070
257 + 31469813 = 31470070
347 + 31469723 = 31470070
449 + 31469621 = 31470070
491 + 31469579 = 31470070
509 + 31469561 = 31470070

Showing the first eight; more decompositions exist.
