Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90270, here are decompositions:

7 + 90263 = 90270
23 + 90247 = 90270
31 + 90239 = 90270
43 + 90227 = 90270
53 + 90217 = 90270
67 + 90203 = 90270
71 + 90199 = 90270
73 + 90197 = 90270

Showing the first eight; more decompositions exist.
