Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542352, here are decompositions:

11 + 31542341 = 31542352
29 + 31542323 = 31542352
71 + 31542281 = 31542352
239 + 31542113 = 31542352
269 + 31542083 = 31542352
419 + 31541933 = 31542352
449 + 31541903 = 31542352
461 + 31541891 = 31542352

Showing the first eight; more decompositions exist.
