Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543588, here are decompositions:

17 + 31543571 = 31543588
59 + 31543529 = 31543588
107 + 31543481 = 31543588
137 + 31543451 = 31543588
191 + 31543397 = 31543588
227 + 31543361 = 31543588
239 + 31543349 = 31543588
257 + 31543331 = 31543588

Showing the first eight; more decompositions exist.
