Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543402, here are decompositions:

5 + 31543397 = 31543402
41 + 31543361 = 31543402
53 + 31543349 = 31543402
71 + 31543331 = 31543402
101 + 31543301 = 31543402
179 + 31543223 = 31543402
239 + 31543163 = 31543402
269 + 31543133 = 31543402

Showing the first eight; more decompositions exist.
