Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469774, here are decompositions:

13 + 31469761 = 31469774
43 + 31469731 = 31469774
103 + 31469671 = 31469774
151 + 31469623 = 31469774
211 + 31469563 = 31469774
307 + 31469467 = 31469774
331 + 31469443 = 31469774
367 + 31469407 = 31469774

Showing the first eight; more decompositions exist.
