Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469718, here are decompositions:

29 + 31469689 = 31469718
47 + 31469671 = 31469718
89 + 31469629 = 31469718
97 + 31469621 = 31469718
131 + 31469587 = 31469718
139 + 31469579 = 31469718
149 + 31469569 = 31469718
157 + 31469561 = 31469718

Showing the first eight; more decompositions exist.
