Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7406, here are decompositions:

13 + 7393 = 7406
37 + 7369 = 7406
73 + 7333 = 7406
97 + 7309 = 7406
109 + 7297 = 7406
163 + 7243 = 7406
193 + 7213 = 7406
199 + 7207 = 7406

Showing the first eight; more decompositions exist.
