Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75122, here are decompositions:
- 13 + 75109 = 75122
- 43 + 75079 = 75122
- 109 + 75013 = 75122
- 163 + 74959 = 75122
- 181 + 74941 = 75122
- 193 + 74929 = 75122
- 199 + 74923 = 75122
- 409 + 74713 = 75122
Showing the first eight; more decompositions exist.
