Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627950, here are decompositions:

19 + 31627931 = 31627950
23 + 31627927 = 31627950
47 + 31627903 = 31627950
61 + 31627889 = 31627950
71 + 31627879 = 31627950
89 + 31627861 = 31627950
139 + 31627811 = 31627950
149 + 31627801 = 31627950

Showing the first eight; more decompositions exist.
