Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499860, here are decompositions:

7 + 499853 = 499860
41 + 499819 = 499860
59 + 499801 = 499860
73 + 499787 = 499860
79 + 499781 = 499860
113 + 499747 = 499860
131 + 499729 = 499860
149 + 499711 = 499860

Showing the first eight; more decompositions exist.
