Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74240, here are decompositions:
- 31 + 74209 = 74240
- 37 + 74203 = 74240
- 43 + 74197 = 74240
- 73 + 74167 = 74240
- 79 + 74161 = 74240
- 97 + 74143 = 74240
- 109 + 74131 = 74240
- 139 + 74101 = 74240
Showing the first eight; more decompositions exist.
