Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482824, here are decompositions:

3 + 31482821 = 31482824
157 + 31482667 = 31482824
181 + 31482643 = 31482824
193 + 31482631 = 31482824
211 + 31482613 = 31482824
313 + 31482511 = 31482824
397 + 31482427 = 31482824
487 + 31482337 = 31482824

Showing the first eight; more decompositions exist.
