Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482872, here are decompositions:

13 + 31482859 = 31482872
73 + 31482799 = 31482872
163 + 31482709 = 31482872
229 + 31482643 = 31482872
241 + 31482631 = 31482872
313 + 31482559 = 31482872
373 + 31482499 = 31482872
433 + 31482439 = 31482872

Showing the first eight; more decompositions exist.
