Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469382, here are decompositions:

29 + 31469353 = 31469382
59 + 31469323 = 31469382
79 + 31469303 = 31469382
83 + 31469299 = 31469382
89 + 31469293 = 31469382
103 + 31469279 = 31469382
173 + 31469209 = 31469382
239 + 31469143 = 31469382

Showing the first eight; more decompositions exist.
