Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482392, here are decompositions:

3 + 31482389 = 31482392
43 + 31482349 = 31482392
163 + 31482229 = 31482392
223 + 31482169 = 31482392
349 + 31482043 = 31482392
379 + 31482013 = 31482392
541 + 31481851 = 31482392
661 + 31481731 = 31482392

Showing the first eight; more decompositions exist.
