Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482782, here are decompositions:

3 + 31482779 = 31482782
73 + 31482709 = 31482782
139 + 31482643 = 31482782
151 + 31482631 = 31482782
223 + 31482559 = 31482782
271 + 31482511 = 31482782
283 + 31482499 = 31482782
433 + 31482349 = 31482782

Showing the first eight; more decompositions exist.
