Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482502, here are decompositions:

3 + 31482499 = 31482502
101 + 31482401 = 31482502
113 + 31482389 = 31482502
383 + 31482119 = 31482502
419 + 31482083 = 31482502
461 + 31482041 = 31482502
521 + 31481981 = 31482502
563 + 31481939 = 31482502

Showing the first eight; more decompositions exist.
