Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468950, here are decompositions:

31 + 31468919 = 31468950
47 + 31468903 = 31468950
89 + 31468861 = 31468950
101 + 31468849 = 31468950
127 + 31468823 = 31468950
157 + 31468793 = 31468950
173 + 31468777 = 31468950
193 + 31468757 = 31468950

Showing the first eight; more decompositions exist.
