Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482230, here are decompositions:

61 + 31482169 = 31482230
127 + 31482103 = 31482230
163 + 31482067 = 31482230
193 + 31482037 = 31482230
331 + 31481899 = 31482230
379 + 31481851 = 31482230
463 + 31481767 = 31482230
487 + 31481743 = 31482230

Showing the first eight; more decompositions exist.
