Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515190, here are decompositions:

17 + 515173 = 515190
37 + 515153 = 515190
41 + 515149 = 515190
47 + 515143 = 515190
79 + 515111 = 515190
101 + 515089 = 515190
103 + 515087 = 515190
149 + 515041 = 515190

Showing the first eight; more decompositions exist.
