Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543420, here are decompositions:

23 + 31543397 = 31543420
59 + 31543361 = 31543420
71 + 31543349 = 31543420
89 + 31543331 = 31543420
197 + 31543223 = 31543420
239 + 31543181 = 31543420
257 + 31543163 = 31543420
317 + 31543103 = 31543420

Showing the first eight; more decompositions exist.
