Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446908, here are decompositions:

37 + 31446871 = 31446908
61 + 31446847 = 31446908
139 + 31446769 = 31446908
151 + 31446757 = 31446908
541 + 31446367 = 31446908
547 + 31446361 = 31446908
811 + 31446097 = 31446908
877 + 31446031 = 31446908

Showing the first eight; more decompositions exist.
