Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74990, here are decompositions:
- 31 + 74959 = 74990
- 61 + 74929 = 74990
- 67 + 74923 = 74990
- 103 + 74887 = 74990
- 163 + 74827 = 74990
- 193 + 74797 = 74990
- 211 + 74779 = 74990
- 229 + 74761 = 74990
Showing the first eight; more decompositions exist.
