Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525254, here are decompositions:

11 + 31525243 = 31525254
41 + 31525213 = 31525254
43 + 31525211 = 31525254
53 + 31525201 = 31525254
71 + 31525183 = 31525254
127 + 31525127 = 31525254
151 + 31525103 = 31525254
223 + 31525031 = 31525254

Showing the first eight; more decompositions exist.
