Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61898, here are decompositions:
- 19 + 61879 = 61898
- 37 + 61861 = 61898
- 61 + 61837 = 61898
- 79 + 61819 = 61898
- 181 + 61717 = 61898
- 211 + 61687 = 61898
- 241 + 61657 = 61898
- 271 + 61627 = 61898
Showing the first eight; more decompositions exist.
