Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469770, here are decompositions:

29 + 31469741 = 31469770
47 + 31469723 = 31469770
149 + 31469621 = 31469770
191 + 31469579 = 31469770
239 + 31469531 = 31469770
251 + 31469519 = 31469770
257 + 31469513 = 31469770
347 + 31469423 = 31469770

Showing the first eight; more decompositions exist.
