Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542242, here are decompositions:
- 13 + 31542229 = 31542242
- 79 + 31542163 = 31542242
- 139 + 31542103 = 31542242
- 211 + 31542031 = 31542242
- 229 + 31542013 = 31542242
- 241 + 31542001 = 31542242
- 271 + 31541971 = 31542242
- 349 + 31541893 = 31542242
Showing the first eight; more decompositions exist.
