Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470358, here are decompositions:

5 + 31470353 = 31470358
137 + 31470221 = 31470358
149 + 31470209 = 31470358
191 + 31470167 = 31470358
509 + 31469849 = 31470358
617 + 31469741 = 31470358
797 + 31469561 = 31470358
827 + 31469531 = 31470358

Showing the first eight; more decompositions exist.
