Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469044, here are decompositions:

3 + 31469041 = 31469044
11 + 31469033 = 31469044
17 + 31469027 = 31469044
251 + 31468793 = 31469044
317 + 31468727 = 31469044
491 + 31468553 = 31469044
521 + 31468523 = 31469044
641 + 31468403 = 31469044

Showing the first eight; more decompositions exist.
