Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446944, here are decompositions:

7 + 31446937 = 31446944
73 + 31446871 = 31446944
97 + 31446847 = 31446944
337 + 31446607 = 31446944
577 + 31446367 = 31446944
691 + 31446253 = 31446944
733 + 31446211 = 31446944
811 + 31446133 = 31446944

Showing the first eight; more decompositions exist.
