Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446242, here are decompositions:

13 + 31446229 = 31446242
19 + 31446223 = 31446242
31 + 31446211 = 31446242
109 + 31446133 = 31446242
181 + 31446061 = 31446242
211 + 31446031 = 31446242
283 + 31445959 = 31446242
313 + 31445929 = 31446242

Showing the first eight; more decompositions exist.
