Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470700, here are decompositions:

47 + 31470653 = 31470700
59 + 31470641 = 31470700
71 + 31470629 = 31470700
137 + 31470563 = 31470700
257 + 31470443 = 31470700
347 + 31470353 = 31470700
479 + 31470221 = 31470700
491 + 31470209 = 31470700

Showing the first eight; more decompositions exist.
