Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543342, here are decompositions:

11 + 31543331 = 31543342
41 + 31543301 = 31543342
179 + 31543163 = 31543342
239 + 31543103 = 31543342
263 + 31543079 = 31543342
401 + 31542941 = 31543342
431 + 31542911 = 31543342
461 + 31542881 = 31543342

Showing the first eight; more decompositions exist.
