Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90518, here are decompositions:

7 + 90511 = 90518
19 + 90499 = 90518
37 + 90481 = 90518
79 + 90439 = 90518
139 + 90379 = 90518
229 + 90289 = 90518
271 + 90247 = 90518
331 + 90187 = 90518

Showing the first eight; more decompositions exist.
