Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75740, here are decompositions:
- 19 + 75721 = 75740
- 31 + 75709 = 75740
- 37 + 75703 = 75740
- 61 + 75679 = 75740
- 157 + 75583 = 75740
- 163 + 75577 = 75740
- 199 + 75541 = 75740
- 229 + 75511 = 75740
Showing the first eight; more decompositions exist.
