Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482698, here are decompositions:

31 + 31482667 = 31482698
67 + 31482631 = 31482698
139 + 31482559 = 31482698
199 + 31482499 = 31482698
271 + 31482427 = 31482698
349 + 31482349 = 31482698
421 + 31482277 = 31482698
601 + 31482097 = 31482698

Showing the first eight; more decompositions exist.
