Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543606, here are decompositions:

257 + 31543349 = 31543606
383 + 31543223 = 31543606
389 + 31543217 = 31543606
443 + 31543163 = 31543606
503 + 31543103 = 31543606
587 + 31543019 = 31543606
797 + 31542809 = 31543606
839 + 31542767 = 31543606

Showing the first eight; more decompositions exist.
