Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456262, here are decompositions:

3 + 31456259 = 31456262
43 + 31456219 = 31456262
139 + 31456123 = 31456262
163 + 31456099 = 31456262
241 + 31456021 = 31456262
373 + 31455889 = 31456262
421 + 31455841 = 31456262
433 + 31455829 = 31456262

Showing the first eight; more decompositions exist.
