Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482300, here are decompositions:

7 + 31482293 = 31482300
19 + 31482281 = 31482300
23 + 31482277 = 31482300
29 + 31482271 = 31482300
43 + 31482257 = 31482300
53 + 31482247 = 31482300
71 + 31482229 = 31482300
127 + 31482173 = 31482300

Showing the first eight; more decompositions exist.
