Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469838, here are decompositions:

41 + 31469797 = 31469838
97 + 31469741 = 31469838
107 + 31469731 = 31469838
149 + 31469689 = 31469838
167 + 31469671 = 31469838
251 + 31469587 = 31469838
269 + 31469569 = 31469838
277 + 31469561 = 31469838

Showing the first eight; more decompositions exist.
