Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499972, here are decompositions:

3 + 499969 = 499972
29 + 499943 = 499972
89 + 499883 = 499972
191 + 499781 = 499972
233 + 499739 = 499972
281 + 499691 = 499972
293 + 499679 = 499972
311 + 499661 = 499972

Showing the first eight; more decompositions exist.
