Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469736, here are decompositions:

5 + 31469731 = 31469736
13 + 31469723 = 31469736
47 + 31469689 = 31469736
83 + 31469653 = 31469736
107 + 31469629 = 31469736
113 + 31469623 = 31469736
149 + 31469587 = 31469736
157 + 31469579 = 31469736

Showing the first eight; more decompositions exist.
