Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456310, here are decompositions:

19 + 31456291 = 31456310
31 + 31456279 = 31456310
73 + 31456237 = 31456310
211 + 31456099 = 31456310
307 + 31456003 = 31456310
349 + 31455961 = 31456310
409 + 31455901 = 31456310
421 + 31455889 = 31456310

Showing the first eight; more decompositions exist.
