Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446958, here are decompositions:

5 + 31446953 = 31446958
41 + 31446917 = 31446958
197 + 31446761 = 31446958
269 + 31446689 = 31446958
317 + 31446641 = 31446958
401 + 31446557 = 31446958
467 + 31446491 = 31446958
617 + 31446341 = 31446958

Showing the first eight; more decompositions exist.
