Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190540, here are decompositions:

3 + 190537 = 190540
11 + 190529 = 190540
17 + 190523 = 190540
131 + 190409 = 190540
137 + 190403 = 190540
149 + 190391 = 190540
173 + 190367 = 190540
227 + 190313 = 190540

Showing the first eight; more decompositions exist.
