Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74988, here are decompositions:
- 29 + 74959 = 74988
- 47 + 74941 = 74988
- 59 + 74929 = 74988
- 97 + 74891 = 74988
- 101 + 74887 = 74988
- 127 + 74861 = 74988
- 131 + 74857 = 74988
- 157 + 74831 = 74988
Showing the first eight; more decompositions exist.
