Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469750, here are decompositions:

19 + 31469731 = 31469750
61 + 31469689 = 31469750
79 + 31469671 = 31469750
97 + 31469653 = 31469750
127 + 31469623 = 31469750
163 + 31469587 = 31469750
181 + 31469569 = 31469750
223 + 31469527 = 31469750

Showing the first eight; more decompositions exist.
