Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543534, here are decompositions:

3 + 31543531 = 31543534
5 + 31543529 = 31543534
53 + 31543481 = 31543534
83 + 31543451 = 31543534
137 + 31543397 = 31543534
173 + 31543361 = 31543534
233 + 31543301 = 31543534
311 + 31543223 = 31543534

Showing the first eight; more decompositions exist.
