Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489834, here are decompositions:

17 + 31489817 = 31489834
83 + 31489751 = 31489834
113 + 31489721 = 31489834
263 + 31489571 = 31489834
293 + 31489541 = 31489834
401 + 31489433 = 31489834
443 + 31489391 = 31489834
587 + 31489247 = 31489834

Showing the first eight; more decompositions exist.
