Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446906, here are decompositions:

13 + 31446893 = 31446906
47 + 31446859 = 31446906
53 + 31446853 = 31446906
59 + 31446847 = 31446906
67 + 31446839 = 31446906
137 + 31446769 = 31446906
149 + 31446757 = 31446906
157 + 31446749 = 31446906

Showing the first eight; more decompositions exist.
