Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534000, here are decompositions:

41 + 31533959 = 31534000
89 + 31533911 = 31534000
167 + 31533833 = 31534000
227 + 31533773 = 31534000
293 + 31533707 = 31534000
359 + 31533641 = 31534000
389 + 31533611 = 31534000
401 + 31533599 = 31534000

Showing the first eight; more decompositions exist.
