Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128024, here are decompositions:
- 3 + 128021 = 128024
- 73 + 127951 = 128024
- 103 + 127921 = 128024
- 151 + 127873 = 128024
- 157 + 127867 = 128024
- 181 + 127843 = 128024
- 277 + 127747 = 128024
- 307 + 127717 = 128024
Showing the first eight; more decompositions exist.
