Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469910, here are decompositions:

7 + 31469903 = 31469910
53 + 31469857 = 31469910
61 + 31469849 = 31469910
97 + 31469813 = 31469910
113 + 31469797 = 31469910
127 + 31469783 = 31469910
149 + 31469761 = 31469910
179 + 31469731 = 31469910

Showing the first eight; more decompositions exist.
