Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446776, here are decompositions:

7 + 31446769 = 31446776
19 + 31446757 = 31446776
37 + 31446739 = 31446776
223 + 31446553 = 31446776
337 + 31446439 = 31446776
349 + 31446427 = 31446776
409 + 31446367 = 31446776
523 + 31446253 = 31446776

Showing the first eight; more decompositions exist.
