Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528314, here are decompositions:

23 + 31528291 = 31528314
31 + 31528283 = 31528314
47 + 31528267 = 31528314
73 + 31528241 = 31528314
101 + 31528213 = 31528314
107 + 31528207 = 31528314
157 + 31528157 = 31528314
163 + 31528151 = 31528314

Showing the first eight; more decompositions exist.
