Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513172, here are decompositions:

3 + 513169 = 513172
5 + 513167 = 513172
41 + 513131 = 513172
71 + 513101 = 513172
89 + 513083 = 513172
113 + 513059 = 513172
131 + 513041 = 513172
173 + 512999 = 513172

Showing the first eight; more decompositions exist.
