Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469772, here are decompositions:

11 + 31469761 = 31469772
31 + 31469741 = 31469772
41 + 31469731 = 31469772
83 + 31469689 = 31469772
101 + 31469671 = 31469772
149 + 31469623 = 31469772
151 + 31469621 = 31469772
193 + 31469579 = 31469772

Showing the first eight; more decompositions exist.
