Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536432, here are decompositions:

29 + 31536403 = 31536432
41 + 31536391 = 31536432
71 + 31536361 = 31536432
73 + 31536359 = 31536432
79 + 31536353 = 31536432
139 + 31536293 = 31536432
229 + 31536203 = 31536432
271 + 31536161 = 31536432

Showing the first eight; more decompositions exist.
