Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40248, here are decompositions:

7 + 40241 = 40248
11 + 40237 = 40248
17 + 40231 = 40248
59 + 40189 = 40248
71 + 40177 = 40248
79 + 40169 = 40248
97 + 40151 = 40248
137 + 40111 = 40248

Showing the first eight; more decompositions exist.
