Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528254, here are decompositions:

13 + 31528241 = 31528254
41 + 31528213 = 31528254
47 + 31528207 = 31528254
83 + 31528171 = 31528254
97 + 31528157 = 31528254
103 + 31528151 = 31528254
127 + 31528127 = 31528254
151 + 31528103 = 31528254

Showing the first eight; more decompositions exist.
