Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543330, here are decompositions:

29 + 31543301 = 31543330
107 + 31543223 = 31543330
113 + 31543217 = 31543330
149 + 31543181 = 31543330
167 + 31543163 = 31543330
197 + 31543133 = 31543330
227 + 31543103 = 31543330
251 + 31543079 = 31543330

Showing the first eight; more decompositions exist.
