Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452984, here are decompositions:

7 + 31452977 = 31452984
11 + 31452973 = 31452984
41 + 31452943 = 31452984
83 + 31452901 = 31452984
181 + 31452803 = 31452984
191 + 31452793 = 31452984
257 + 31452727 = 31452984
263 + 31452721 = 31452984

Showing the first eight; more decompositions exist.
