Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539794, here are decompositions:

31 + 31539763 = 31539794
37 + 31539757 = 31539794
67 + 31539727 = 31539794
151 + 31539643 = 31539794
211 + 31539583 = 31539794
271 + 31539523 = 31539794
373 + 31539421 = 31539794
457 + 31539337 = 31539794

Showing the first eight; more decompositions exist.
