Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469302, here are decompositions:

3 + 31469299 = 31469302
23 + 31469279 = 31469302
233 + 31469069 = 31469302
269 + 31469033 = 31469302
383 + 31468919 = 31469302
401 + 31468901 = 31469302
479 + 31468823 = 31469302
509 + 31468793 = 31469302

Showing the first eight; more decompositions exist.
