Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469384, here are decompositions:

31 + 31469353 = 31469384
61 + 31469323 = 31469384
97 + 31469287 = 31469384
241 + 31469143 = 31469384
283 + 31469101 = 31469384
421 + 31468963 = 31469384
523 + 31468861 = 31469384
607 + 31468777 = 31469384

Showing the first eight; more decompositions exist.
