Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97890, here are decompositions:
- 7 + 97883 = 97890
- 11 + 97879 = 97890
- 19 + 97871 = 97890
- 29 + 97861 = 97890
- 31 + 97859 = 97890
- 41 + 97849 = 97890
- 43 + 97847 = 97890
- 47 + 97843 = 97890
Showing the first eight; more decompositions exist.
