Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482428, here are decompositions:

79 + 31482349 = 31482428
151 + 31482277 = 31482428
157 + 31482271 = 31482428
181 + 31482247 = 31482428
199 + 31482229 = 31482428
331 + 31482097 = 31482428
541 + 31481887 = 31482428
577 + 31481851 = 31482428

Showing the first eight; more decompositions exist.
