Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75000, here are decompositions:
- 41 + 74959 = 75000
- 59 + 74941 = 75000
- 67 + 74933 = 75000
- 71 + 74929 = 75000
- 97 + 74903 = 75000
- 103 + 74897 = 75000
- 109 + 74891 = 75000
- 113 + 74887 = 75000
Showing the first eight; more decompositions exist.
