Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482494, here are decompositions:

67 + 31482427 = 31482494
151 + 31482343 = 31482494
157 + 31482337 = 31482494
223 + 31482271 = 31482494
397 + 31482097 = 31482494
457 + 31482037 = 31482494
607 + 31481887 = 31482494
643 + 31481851 = 31482494

Showing the first eight; more decompositions exist.
