Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446582, here are decompositions:

19 + 31446563 = 31446582
29 + 31446553 = 31446582
241 + 31446341 = 31446582
331 + 31446251 = 31446582
353 + 31446229 = 31446582
359 + 31446223 = 31446582
449 + 31446133 = 31446582
521 + 31446061 = 31446582

Showing the first eight; more decompositions exist.
