Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482580, here are decompositions:

11 + 31482569 = 31482580
29 + 31482551 = 31482580
71 + 31482509 = 31482580
179 + 31482401 = 31482580
191 + 31482389 = 31482580
401 + 31482179 = 31482580
461 + 31482119 = 31482580
491 + 31482089 = 31482580

Showing the first eight; more decompositions exist.
