Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470196, here are decompositions:

3 + 31470193 = 31470196
29 + 31470167 = 31470196
53 + 31470143 = 31470196
293 + 31469903 = 31470196
347 + 31469849 = 31470196
383 + 31469813 = 31470196
617 + 31469579 = 31470196
677 + 31469519 = 31470196

Showing the first eight; more decompositions exist.
