Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40190, here are decompositions:

13 + 40177 = 40190
37 + 40153 = 40190
61 + 40129 = 40190
67 + 40123 = 40190
79 + 40111 = 40190
97 + 40093 = 40190
103 + 40087 = 40190
127 + 40063 = 40190

Showing the first eight; more decompositions exist.
