Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446256, here are decompositions:

3 + 31446253 = 31446256
5 + 31446251 = 31446256
29 + 31446227 = 31446256
89 + 31446167 = 31446256
467 + 31445789 = 31446256
563 + 31445693 = 31446256
593 + 31445663 = 31446256
683 + 31445573 = 31446256

Showing the first eight; more decompositions exist.
