Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190372, here are decompositions:

3 + 190369 = 190372
5 + 190367 = 190372
41 + 190331 = 190372
59 + 190313 = 190372
71 + 190301 = 190372
89 + 190283 = 190372
101 + 190271 = 190372
191 + 190181 = 190372

Showing the first eight; more decompositions exist.
