Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543006, here are decompositions:

149 + 31542857 = 31543006
179 + 31542827 = 31543006
197 + 31542809 = 31543006
239 + 31542767 = 31543006
347 + 31542659 = 31543006
419 + 31542587 = 31543006
569 + 31542437 = 31543006
587 + 31542419 = 31543006

Showing the first eight; more decompositions exist.
