Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448966, here are decompositions:

67 + 31448899 = 31448966
103 + 31448863 = 31448966
127 + 31448839 = 31448966
163 + 31448803 = 31448966
379 + 31448587 = 31448966
433 + 31448533 = 31448966
487 + 31448479 = 31448966
643 + 31448323 = 31448966

Showing the first eight; more decompositions exist.
