Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456226, here are decompositions:

7 + 31456219 = 31456226
103 + 31456123 = 31456226
127 + 31456099 = 31456226
223 + 31456003 = 31456226
337 + 31455889 = 31456226
349 + 31455877 = 31456226
367 + 31455859 = 31456226
397 + 31455829 = 31456226

Showing the first eight; more decompositions exist.
