Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543598, here are decompositions:

19 + 31543579 = 31543598
67 + 31543531 = 31543598
109 + 31543489 = 31543598
367 + 31543231 = 31543598
379 + 31543219 = 31543598
607 + 31542991 = 31543598
631 + 31542967 = 31543598
661 + 31542937 = 31543598

Showing the first eight; more decompositions exist.
