Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513048, here are decompositions:

7 + 513041 = 513048
17 + 513031 = 513048
31 + 513017 = 513048
47 + 513001 = 513048
59 + 512989 = 513048
71 + 512977 = 513048
89 + 512959 = 513048
127 + 512921 = 513048

Showing the first eight; more decompositions exist.
