Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534522, here are decompositions:

29 + 31534493 = 31534522
179 + 31534343 = 31534522
251 + 31534271 = 31534522
281 + 31534241 = 31534522
353 + 31534169 = 31534522
401 + 31534121 = 31534522
419 + 31534103 = 31534522
443 + 31534079 = 31534522

Showing the first eight; more decompositions exist.
