Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543474, here are decompositions:

23 + 31543451 = 31543474
113 + 31543361 = 31543474
173 + 31543301 = 31543474
251 + 31543223 = 31543474
257 + 31543217 = 31543474
293 + 31543181 = 31543474
311 + 31543163 = 31543474
503 + 31542971 = 31543474

Showing the first eight; more decompositions exist.
