Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498734, here are decompositions:

31 + 31498703 = 31498734
193 + 31498541 = 31498734
263 + 31498471 = 31498734
271 + 31498463 = 31498734
307 + 31498427 = 31498734
313 + 31498421 = 31498734
367 + 31498367 = 31498734
457 + 31498277 = 31498734

Showing the first eight; more decompositions exist.
