Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461076, here are decompositions:

29 + 31461047 = 31461076
149 + 31460927 = 31461076
197 + 31460879 = 31461076
239 + 31460837 = 31461076
293 + 31460783 = 31461076
347 + 31460729 = 31461076
359 + 31460717 = 31461076
419 + 31460657 = 31461076

Showing the first eight; more decompositions exist.
