Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542698, here are decompositions:
- 67 + 31542631 = 31542698
- 139 + 31542559 = 31542698
- 151 + 31542547 = 31542698
- 211 + 31542487 = 31542698
- 241 + 31542457 = 31542698
- 307 + 31542391 = 31542698
- 631 + 31542067 = 31542698
- 661 + 31542037 = 31542698
Showing the first eight; more decompositions exist.
