Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446006, here are decompositions:

23 + 31445983 = 31446006
29 + 31445977 = 31446006
47 + 31445959 = 31446006
89 + 31445917 = 31446006
157 + 31445849 = 31446006
173 + 31445833 = 31446006
283 + 31445723 = 31446006
313 + 31445693 = 31446006

Showing the first eight; more decompositions exist.
