Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543354, here are decompositions:

5 + 31543349 = 31543354
23 + 31543331 = 31543354
53 + 31543301 = 31543354
131 + 31543223 = 31543354
137 + 31543217 = 31543354
173 + 31543181 = 31543354
191 + 31543163 = 31543354
251 + 31543103 = 31543354

Showing the first eight; more decompositions exist.
