Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455332, here are decompositions:

19 + 31455313 = 31455332
31 + 31455301 = 31455332
61 + 31455271 = 31455332
109 + 31455223 = 31455332
193 + 31455139 = 31455332
211 + 31455121 = 31455332
229 + 31455103 = 31455332
379 + 31454953 = 31455332

Showing the first eight; more decompositions exist.
