Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91504, here are decompositions:

5 + 91499 = 91504
11 + 91493 = 91504
41 + 91463 = 91504
47 + 91457 = 91504
71 + 91433 = 91504
107 + 91397 = 91504
131 + 91373 = 91504
137 + 91367 = 91504

Showing the first eight; more decompositions exist.
