Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543450, here are decompositions:

53 + 31543397 = 31543450
89 + 31543361 = 31543450
101 + 31543349 = 31543450
149 + 31543301 = 31543450
227 + 31543223 = 31543450
233 + 31543217 = 31543450
269 + 31543181 = 31543450
317 + 31543133 = 31543450

Showing the first eight; more decompositions exist.
