Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469562, here are decompositions:

31 + 31469531 = 31469562
43 + 31469519 = 31469562
139 + 31469423 = 31469562
151 + 31469411 = 31469562
239 + 31469323 = 31469562
263 + 31469299 = 31469562
269 + 31469293 = 31469562
283 + 31469279 = 31469562

Showing the first eight; more decompositions exist.
