Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91442, here are decompositions:

19 + 91423 = 91442
31 + 91411 = 91442
61 + 91381 = 91442
73 + 91369 = 91442
139 + 91303 = 91442
151 + 91291 = 91442
193 + 91249 = 91442
199 + 91243 = 91442

Showing the first eight; more decompositions exist.
