Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543576, here are decompositions:

5 + 31543571 = 31543576
47 + 31543529 = 31543576
179 + 31543397 = 31543576
227 + 31543349 = 31543576
353 + 31543223 = 31543576
359 + 31543217 = 31543576
443 + 31543133 = 31543576
509 + 31543067 = 31543576

Showing the first eight; more decompositions exist.
