Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024140, here are decompositions:
- 37 + 1024103 = 1024140
- 41 + 1024099 = 1024140
- 53 + 1024087 = 1024140
- 67 + 1024073 = 1024140
- 79 + 1024061 = 1024140
- 109 + 1024031 = 1024140
- 149 + 1023991 = 1024140
- 163 + 1023977 = 1024140
Showing the first eight; more decompositions exist.
