Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89240, here are decompositions:

3 + 89237 = 89240
13 + 89227 = 89240
31 + 89209 = 89240
37 + 89203 = 89240
103 + 89137 = 89240
127 + 89113 = 89240
139 + 89101 = 89240
157 + 89083 = 89240

Showing the first eight; more decompositions exist.
