Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469922, here are decompositions:

19 + 31469903 = 31469922
61 + 31469861 = 31469922
73 + 31469849 = 31469922
109 + 31469813 = 31469922
139 + 31469783 = 31469922
181 + 31469741 = 31469922
191 + 31469731 = 31469922
199 + 31469723 = 31469922

Showing the first eight; more decompositions exist.
