Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482798, here are decompositions:

19 + 31482779 = 31482798
37 + 31482761 = 31482798
89 + 31482709 = 31482798
131 + 31482667 = 31482798
157 + 31482641 = 31482798
167 + 31482631 = 31482798
181 + 31482617 = 31482798
199 + 31482599 = 31482798

Showing the first eight; more decompositions exist.
