Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993240, here are decompositions:
- 7 + 993233 = 993240
- 23 + 993217 = 993240
- 29 + 993211 = 993240
- 37 + 993203 = 993240
- 41 + 993199 = 993240
- 43 + 993197 = 993240
- 71 + 993169 = 993240
- 103 + 993137 = 993240
Showing the first eight; more decompositions exist.
