Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75126, here are decompositions:
- 17 + 75109 = 75126
- 43 + 75083 = 75126
- 47 + 75079 = 75126
- 89 + 75037 = 75126
- 97 + 75029 = 75126
- 109 + 75017 = 75126
- 113 + 75013 = 75126
- 167 + 74959 = 75126
Showing the first eight; more decompositions exist.
