Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542104, here are decompositions:
- 37 + 31542067 = 31542104
- 67 + 31542037 = 31542104
- 73 + 31542031 = 31542104
- 103 + 31542001 = 31542104
- 127 + 31541977 = 31542104
- 211 + 31541893 = 31542104
- 277 + 31541827 = 31542104
- 367 + 31541737 = 31542104
Showing the first eight; more decompositions exist.
