Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456376, here are decompositions:

97 + 31456279 = 31456376
139 + 31456237 = 31456376
157 + 31456219 = 31456376
277 + 31456099 = 31456376
283 + 31456093 = 31456376
373 + 31456003 = 31456376
487 + 31455889 = 31456376
499 + 31455877 = 31456376

Showing the first eight; more decompositions exist.
