Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499880, here are decompositions:

61 + 499819 = 499880
79 + 499801 = 499880
151 + 499729 = 499880
163 + 499717 = 499880
193 + 499687 = 499880
211 + 499669 = 499880
331 + 499549 = 499880
373 + 499507 = 499880

Showing the first eight; more decompositions exist.
