Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482812, here are decompositions:

13 + 31482799 = 31482812
103 + 31482709 = 31482812
181 + 31482631 = 31482812
199 + 31482613 = 31482812
313 + 31482499 = 31482812
373 + 31482439 = 31482812
463 + 31482349 = 31482812
541 + 31482271 = 31482812

Showing the first eight; more decompositions exist.
