Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483950, here are decompositions:

23 + 31483927 = 31483950
31 + 31483919 = 31483950
37 + 31483913 = 31483950
61 + 31483889 = 31483950
67 + 31483883 = 31483950
73 + 31483877 = 31483950
79 + 31483871 = 31483950
89 + 31483861 = 31483950

Showing the first eight; more decompositions exist.
