Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482460, here are decompositions:

59 + 31482401 = 31482460
71 + 31482389 = 31482460
167 + 31482293 = 31482460
179 + 31482281 = 31482460
281 + 31482179 = 31482460
293 + 31482167 = 31482460
419 + 31482041 = 31482460
479 + 31481981 = 31482460

Showing the first eight; more decompositions exist.
