Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61870, here are decompositions:
- 89 + 61781 = 61870
- 113 + 61757 = 61870
- 167 + 61703 = 61870
- 197 + 61673 = 61870
- 227 + 61643 = 61870
- 233 + 61637 = 61870
- 239 + 61631 = 61870
- 257 + 61613 = 61870
Showing the first eight; more decompositions exist.
