Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513090, here are decompositions:

7 + 513083 = 513090
23 + 513067 = 513090
31 + 513059 = 513090
37 + 513053 = 513090
43 + 513047 = 513090
59 + 513031 = 513090
73 + 513017 = 513090
89 + 513001 = 513090

Showing the first eight; more decompositions exist.
