Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455674, here are decompositions:

37 + 31455637 = 31455674
43 + 31455631 = 31455674
241 + 31455433 = 31455674
277 + 31455397 = 31455674
307 + 31455367 = 31455674
373 + 31455301 = 31455674
571 + 31455103 = 31455674
643 + 31455031 = 31455674

Showing the first eight; more decompositions exist.
