Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469170, here are decompositions:

101 + 31469069 = 31469170
137 + 31469033 = 31469170
251 + 31468919 = 31469170
269 + 31468901 = 31469170
347 + 31468823 = 31469170
443 + 31468727 = 31469170
503 + 31468667 = 31469170
599 + 31468571 = 31469170

Showing the first eight; more decompositions exist.
