Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446476, here are decompositions:

37 + 31446439 = 31446476
109 + 31446367 = 31446476
223 + 31446253 = 31446476
379 + 31446097 = 31446476
409 + 31446067 = 31446476
499 + 31445977 = 31446476
547 + 31445929 = 31446476
613 + 31445863 = 31446476

Showing the first eight; more decompositions exist.
