Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460950, here are decompositions:

23 + 31460927 = 31460950
71 + 31460879 = 31460950
113 + 31460837 = 31460950
167 + 31460783 = 31460950
233 + 31460717 = 31460950
293 + 31460657 = 31460950
401 + 31460549 = 31460950
467 + 31460483 = 31460950

Showing the first eight; more decompositions exist.
