Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469206, here are decompositions:

29 + 31469177 = 31469206
137 + 31469069 = 31469206
173 + 31469033 = 31469206
179 + 31469027 = 31469206
239 + 31468967 = 31469206
383 + 31468823 = 31469206
449 + 31468757 = 31469206
479 + 31468727 = 31469206

Showing the first eight; more decompositions exist.
