Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469726, here are decompositions:

3 + 31469723 = 31469726
37 + 31469689 = 31469726
73 + 31469653 = 31469726
97 + 31469629 = 31469726
103 + 31469623 = 31469726
139 + 31469587 = 31469726
157 + 31469569 = 31469726
163 + 31469563 = 31469726

Showing the first eight; more decompositions exist.
