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.
