Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476740, here are decompositions:

7 + 31476733 = 31476740
13 + 31476727 = 31476740
37 + 31476703 = 31476740
109 + 31476631 = 31476740
193 + 31476547 = 31476740
223 + 31476517 = 31476740
241 + 31476499 = 31476740
283 + 31476457 = 31476740

Showing the first eight; more decompositions exist.
