Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128974, here are decompositions:
- 3 + 128971 = 128974
- 5 + 128969 = 128974
- 23 + 128951 = 128974
- 71 + 128903 = 128974
- 101 + 128873 = 128974
- 113 + 128861 = 128974
- 137 + 128837 = 128974
- 227 + 128747 = 128974
Showing the first eight; more decompositions exist.
