Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542038, here are decompositions:
- 7 + 31542031 = 31542038
- 37 + 31542001 = 31542038
- 61 + 31541977 = 31542038
- 67 + 31541971 = 31542038
- 139 + 31541899 = 31542038
- 181 + 31541857 = 31542038
- 211 + 31541827 = 31542038
- 277 + 31541761 = 31542038
Showing the first eight; more decompositions exist.
