Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91790, here are decompositions:

19 + 91771 = 91790
37 + 91753 = 91790
79 + 91711 = 91790
151 + 91639 = 91790
199 + 91591 = 91790
277 + 91513 = 91790
331 + 91459 = 91790
337 + 91453 = 91790

Showing the first eight; more decompositions exist.
