Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993180, here are decompositions:

11 + 993169 = 993180
43 + 993137 = 993180
59 + 993121 = 993180
73 + 993107 = 993180
101 + 993079 = 993180
127 + 993053 = 993180
131 + 993049 = 993180
179 + 993001 = 993180

Showing the first eight; more decompositions exist.
