Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482098, here are decompositions:

31 + 31482067 = 31482098
61 + 31482037 = 31482098
199 + 31481899 = 31482098
211 + 31481887 = 31482098
331 + 31481767 = 31482098
367 + 31481731 = 31482098
397 + 31481701 = 31482098
421 + 31481677 = 31482098

Showing the first eight; more decompositions exist.
