Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482610, here are decompositions:

11 + 31482599 = 31482610
23 + 31482587 = 31482610
41 + 31482569 = 31482610
59 + 31482551 = 31482610
101 + 31482509 = 31482610
317 + 31482293 = 31482610
353 + 31482257 = 31482610
431 + 31482179 = 31482610

Showing the first eight; more decompositions exist.
