Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482992, here are decompositions:

19 + 31482973 = 31482992
103 + 31482889 = 31482992
193 + 31482799 = 31482992
283 + 31482709 = 31482992
349 + 31482643 = 31482992
379 + 31482613 = 31482992
433 + 31482559 = 31482992
643 + 31482349 = 31482992

Showing the first eight; more decompositions exist.
