Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464018, here are decompositions:

17 + 31464001 = 31464018
59 + 31463959 = 31464018
97 + 31463921 = 31464018
107 + 31463911 = 31464018
109 + 31463909 = 31464018
127 + 31463891 = 31464018
139 + 31463879 = 31464018
191 + 31463827 = 31464018

Showing the first eight; more decompositions exist.
