Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460400, here are decompositions:

31 + 31460369 = 31460400
53 + 31460347 = 31460400
61 + 31460339 = 31460400
71 + 31460329 = 31460400
79 + 31460321 = 31460400
107 + 31460293 = 31460400
109 + 31460291 = 31460400
137 + 31460263 = 31460400

Showing the first eight; more decompositions exist.
