Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548950, here are decompositions:

79 + 31548871 = 31548950
127 + 31548823 = 31548950
193 + 31548757 = 31548950
211 + 31548739 = 31548950
331 + 31548619 = 31548950
337 + 31548613 = 31548950
373 + 31548577 = 31548950
523 + 31548427 = 31548950

Showing the first eight; more decompositions exist.
