Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446008, here are decompositions:

31 + 31445977 = 31446008
67 + 31445941 = 31446008
79 + 31445929 = 31446008
157 + 31445851 = 31446008
331 + 31445677 = 31446008
367 + 31445641 = 31446008
397 + 31445611 = 31446008
421 + 31445587 = 31446008

Showing the first eight; more decompositions exist.
