Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456334, here are decompositions:

3 + 31456331 = 31456334
43 + 31456291 = 31456334
97 + 31456237 = 31456334
211 + 31456123 = 31456334
241 + 31456093 = 31456334
313 + 31456021 = 31456334
331 + 31456003 = 31456334
373 + 31455961 = 31456334

Showing the first eight; more decompositions exist.
