Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468932, here are decompositions:

13 + 31468919 = 31468932
29 + 31468903 = 31468932
31 + 31468901 = 31468932
71 + 31468861 = 31468932
83 + 31468849 = 31468932
109 + 31468823 = 31468932
139 + 31468793 = 31468932
233 + 31468699 = 31468932

Showing the first eight; more decompositions exist.
