Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482432, here are decompositions:

5 + 31482427 = 31482432
31 + 31482401 = 31482432
43 + 31482389 = 31482432
83 + 31482349 = 31482432
89 + 31482343 = 31482432
139 + 31482293 = 31482432
151 + 31482281 = 31482432
263 + 31482169 = 31482432

Showing the first eight; more decompositions exist.
