Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469730, here are decompositions:

7 + 31469723 = 31469730
41 + 31469689 = 31469730
59 + 31469671 = 31469730
101 + 31469629 = 31469730
107 + 31469623 = 31469730
109 + 31469621 = 31469730
151 + 31469579 = 31469730
167 + 31469563 = 31469730

Showing the first eight; more decompositions exist.
