Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543302, here are decompositions:

29 + 31543273 = 31543302
59 + 31543243 = 31543302
71 + 31543231 = 31543302
79 + 31543223 = 31543302
83 + 31543219 = 31543302
139 + 31543163 = 31543302
199 + 31543103 = 31543302
223 + 31543079 = 31543302

Showing the first eight; more decompositions exist.
