Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484372, here are decompositions:

13 + 31484359 = 31484372
19 + 31484353 = 31484372
163 + 31484209 = 31484372
193 + 31484179 = 31484372
211 + 31484161 = 31484372
229 + 31484143 = 31484372
313 + 31484059 = 31484372
571 + 31483801 = 31484372

Showing the first eight; more decompositions exist.
