Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75240, here are decompositions:
- 13 + 75227 = 75240
- 17 + 75223 = 75240
- 23 + 75217 = 75240
- 29 + 75211 = 75240
- 31 + 75209 = 75240
- 47 + 75193 = 75240
- 59 + 75181 = 75240
- 71 + 75169 = 75240
Showing the first eight; more decompositions exist.
