Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461254, here are decompositions:

31 + 31461223 = 31461254
61 + 31461193 = 31461254
73 + 31461181 = 31461254
127 + 31461127 = 31461254
241 + 31461013 = 31461254
277 + 31460977 = 31461254
283 + 31460971 = 31461254
337 + 31460917 = 31461254

Showing the first eight; more decompositions exist.
