Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446526, here are decompositions:

197 + 31446329 = 31446526
269 + 31446257 = 31446526
359 + 31446167 = 31446526
569 + 31445957 = 31446526
677 + 31445849 = 31446526
863 + 31445663 = 31446526
953 + 31445573 = 31446526
983 + 31445543 = 31446526

Showing the first eight; more decompositions exist.
