Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91240, here are decompositions:

3 + 91237 = 91240
11 + 91229 = 91240
41 + 91199 = 91240
47 + 91193 = 91240
89 + 91151 = 91240
101 + 91139 = 91240
113 + 91127 = 91240
251 + 90989 = 91240

Showing the first eight; more decompositions exist.
