Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469670, here are decompositions:

17 + 31469653 = 31469670
41 + 31469629 = 31469670
47 + 31469623 = 31469670
83 + 31469587 = 31469670
101 + 31469569 = 31469670
107 + 31469563 = 31469670
109 + 31469561 = 31469670
139 + 31469531 = 31469670

Showing the first eight; more decompositions exist.
